What does the E25 error code mean on a Bosch dishwasher?

The E25 error code on a Bosch dishwasher indicates that the drain pump is blocked or its cover is not properly secured. This is a more specific drainage issue than E24 — it points directly to a physical obstruction inside or around the drain pump housing rather than a general draining failure.

What is the difference between E24 and E25 on a Bosch dishwasher?

E24 indicates a general drainage failure where the dishwasher cannot drain water at the end of a cycle. E25 is more specific and points to a blockage at the drain pump itself or an improperly fitted drain pump cover. Both errors are related to drainage but E25 typically requires direct access to the drain pump to resolve.

How do I fix the E25 error on my Bosch dishwasher?

First, remove and clean the filter at the bottom of the dishwasher tub. Then locate the drain pump cover, typically found beneath the filter assembly, and check that it is securely locked in place. Remove any visible debris blocking the pump impeller. If the error persists after these steps, the drain pump may need professional inspection or replacement.

Can I fix the Bosch E25 error myself?

In many cases, yes. Clearing debris from the drain pump and reseating the pump cover can be done at home without special tools. However, if the blockage is deeper inside the pump or the pump motor is damaged, it is best to contact a certified appliance repair technician to avoid further damage.

Bosch Dishwasher E25 Error Code — Drain Pump Blocked or Pump Cover Loose

DIY Fix — 20 Minutes Also shown as: E-25 E 25 E:25

Quick Answer

The E25 error code means Bosch's control board has detected a drain pump problem — confirmed by Bosch's own official support page as either a blocked pump or a loose/missing pump cover. Nine times out of ten this is a free 20-minute DIY fix: remove the filter, reseat the white plastic pump cover until it clicks, and clear any debris from the pump impeller. A small object like a fruit stone, glass shard, or seed is the most frequent culprit. An actual failed pump motor is rare and only needs considering once the impeller is confirmed clear and the cover is correctly seated.

E22

Filter / sump blocked. Fix: clean the three-part filter. Pump is typically fine.

E24

Drain path blocked downstream (hose, disposal, air gap). Pump is working but water can't exit.

This code

E25

Drain pump itself blocked or pump cover is loose/missing. Impeller jammed or cover unseated.

What the E25 Code Means

Bosch's official definition of E25 is precise: the drain pump is blocked, or the drain pump cover is loose or missing. The control board monitors the pump motor's electrical load. When the impeller hits a solid object — a fruit stone, glass shard, olive pit, twist-tie — the resistance spikes and the board shuts the motor down before it burns out, then raises E25. The same code appears if the white plastic pump cover (the disc that sits over the pump assembly in the sump) is not fully snapped into its locked position, because a loose cover lets water bypass the impeller rather than being pushed through it.

You will almost always see standing water pooled in the bottom of the tub alongside E25, and you may hear a brief grinding or buzzing sound right before the code appears — the sound of the impeller fighting against an obstruction before the board cuts power to the motor.

The good news, confirmed by appliance repair professionals with extensive E25 call histories, is that a new drain pump is rarely needed. The fix is clearing the blockage from inside the sump — a job that requires no tools, no parts, and no experience, just rubber gloves and a spoon to reseat the pump cover if it's lifted.

Three components involved in E25

⚪

Pump cover (most common E25 cause)

White plastic disc over the drain pump in the sump. Must be fully snapped in and flat — not tilted or partially lifted. Use a spoon to press it down until it clicks.

🔄

Pump impeller

Spinning plastic vane that pushes water out. A single fruit pit or shard of glass jammed here is the most frequent physical cause of E25. Must rotate freely.

⚡

Pump motor

The motor driving the impeller. Rarely the actual problem — only suspect it after the impeller is confirmed clear and the cover is correctly seated and E25 still returns.

Common Causes — Most Likely First

Drain pump cover loose, tilted, or not clicked in. The white plastic disc over the pump assembly in the sump has popped up or was not fully reseated after a previous filter clean. A loose cover allows water to bypass the impeller entirely — the pump spins but moves nothing. Reseating it until it clicks flat is the fastest possible E25 fix. Very common

Foreign object jammed in the pump impeller. A fruit stone (olive, cherry, avocado), glass shard, seed, small bone fragment, twist-tie, or label has passed through the filter and lodged between the impeller blades, preventing rotation. The board detects the stalled motor and raises E25 to prevent burn-out. Very common

Clogged or dirty filter assembly contributing to pump overload. Severe filter clogging forces the pump to work much harder to draw water through, and the elevated motor load can register as a pump blockage. Cleaning the filter is always the first step before opening the pump area. Common

Cracked or damaged pump cover. The pump cover has developed a crack, warp, or broken locking tab that prevents it from seating correctly. Even a hairline crack can let enough water bypass the impeller to trigger E25. A cracked cover cannot be repaired — it needs a replacement part. Occasional

Grease and debris buildup around the impeller housing. Over a long period without cleaning, accumulated grease can thicken to the point where it restricts the impeller's rotation without a single hard foreign object being present. A thorough clean of the pump area resolves this. Occasional

Torn or damaged filter mesh allowing debris to reach the pump. A small tear or warp in the fine mesh floor filter creates a gap through which hard particles pass directly into the pump. If E25 recurs repeatedly despite regular cleaning, inspect the mesh for damage. Less common

Failed drain pump motor. The motor windings have burned out or the impeller assembly has physically seized beyond what a debris clear can fix. The pump draws no current or incorrect current, and E25 appears even with the cover correctly seated and the pump area completely clear. Requires pump replacement. Rare — needs technician

How to Fix the E25 Error — Step by Step

Switch off power and remove standing water

Turn the dishwasher off at the breaker or unplug it. Open the door and use a sponge or cup to remove any standing water from the tub floor — the clearer the sump is, the easier it will be to see and reach the pump cover and impeller. Remove the bottom dish rack and set it aside.

Wear rubber gloves from this point on. Broken glass is the single most common object found in a jammed Bosch pump impeller, and it is not always visible to the naked eye in murky water.

Clean the filter assembly

Rotate the cylindrical mesh filter counter-clockwise and lift it out. Remove the flat coarse filter beneath it and then the fine mesh floor panel. Rinse all three under warm running water with a soft brush. This is Bosch's official first step before the pump check, and it eliminates the filter as a contributing cause. Reinstall will happen after the pump cover check.

Check and reseat the pump cover

With the filters removed, look down into the sump and locate the white plastic pump cover — a flat disc sitting over the drain pump inlet, approximately 3–4 inches across. Press it with your finger. If it rocks, lifts, or feels loose at any edge, it was not fully seated — this alone is likely the E25 cause. Use the bowl of a teaspoon or the tip of a flathead screwdriver to press around the cover's locking tabs until it clicks flat and no longer moves. The cover should be completely level and firm.

Just cleaned the filter? The pump cover is frequently dislodged during filter removal and reinstallation, even by experienced users who don't notice. This is the most common reason E25 appears immediately after a routine maintenance clean.

Open the pump cover and inspect the impeller

To check for blockages inside the pump, the cover needs to come off. Using the bowl of a spoon, locate the small pry tab or slot on the cover edge and lever it up until it clicks open. Grip the cover and pull upward until you feel resistance, then pull forward to detach it completely. Set it aside. Now look into the pump housing with a flashlight and, wearing rubber gloves, carefully feel for and remove any debris — glass fragments, seeds, pits, labels, or grit — from around and between the impeller blades. Try to rotate the impeller by hand; it should turn with a small, smooth resistance. If it's stuck fast, there is still debris in the housing — continue clearing it.

Use needle-nose pliers to extract glass shards rather than reaching for them blindly with bare fingers.

Inspect the pump cover itself for damage

Before reinstalling the cover, examine it carefully for cracks, chips, or a broken locking tab. Hold it up to a light source — cracks are sometimes only visible as a shadow. A cracked cover cannot seal correctly and will cause repeated E25 errors even after the impeller is cleared. If damaged, order a replacement cover for your specific Bosch model number before continuing.

Reinstall the pump cover and filters

Lower the pump cover into the housing — the flat side down, the pry tab accessible. Press it firmly into the locked position until you hear and feel it click flat. There should be no movement or rocking when you press any part of the cover. Reinstall the fine mesh floor panel, then the flat coarse filter, then the cylindrical filter — rotating it clockwise until it locks. Reinstall the bottom rack.

Reset the dishwasher and run a monitored test cycle

Restore power at the breaker. Press and hold the Start button for 3–5 seconds until the display shows a 1-minute reset cycle — let it complete without opening the door. Then run a short rinse or quick wash cycle while staying beside the machine. Listen for the drain pump activating cleanly near the end without grinding, and watch for standing water after the cycle ends. If the machine drains fully and E25 does not return, the fix is complete.

If E25 returns with a clear impeller and correctly seated, undamaged cover, the drain pump motor has likely failed and needs replacement — at this point book a technician.

When to Call a Technician

Reseating the pump cover and clearing the impeller resolves E25 in the vast majority of cases. Book a professional repair if:

E25 returns after the impeller has been thoroughly cleared and the cover is confirmed fully seated and undamaged
The pump makes a humming or buzzing sound during the drain phase but water does not move
The impeller does not rotate at all — even with no visible debris — indicating a seized motor
The pump cover is cracked or has a broken locking tab and needs a replacement part
E25 recurs repeatedly over several weeks despite regular cleaning — check the filter mesh for tears that are allowing debris to reach the pump continuously
The pump is silent during the drain phase — the motor may have completely failed

Frequently Asked Questions

What is the pump cover and why does it cause E25 when loose?

The pump cover is a white plastic disc that sits over the drain pump assembly in the sump at the bottom of the tub. Its job is to force water down through the impeller channel so the pump can push it out the drain hose. When the cover is loose, lifted, or cracked, water bypasses the impeller and just circulates in the open sump instead of being pumped out. The motor spins in effectively open water, moves no water, the tub stays full, and the board raises E25. Snapping the cover back down flat — until it clicks — is often the entire fix.

E25 appeared right after I cleaned my filter. Why?

The pump cover is the most common casualty of a filter cleaning session. When you remove the cylindrical filter and the flat filter beneath it, the pump cover sits exposed in the sump and is very easily nudged, tilted, or partially lifted in the process. Many people don't notice it moved because it looks flat but isn't fully clicked in. After any filter clean, press the pump cover firmly until you feel it click — that single step prevents the majority of post-maintenance E25 errors.

What kinds of objects typically cause E25 by jamming the impeller?

The most frequently retrieved items are fruit stones (cherry pits, olive pits, avocado seeds, lemon seeds), glass shards from broken items in the wash, small bones or gristle fragments, toothpicks, twist-ties, and small food labels or stickers that slipped off jars. Hard, small objects that can pass through a slightly worn filter mesh are the primary risk. Pre-scraping plates and removing labels before loading significantly reduces E25 frequency.

Can I run the dishwasher without the pump cover?

No — do not run the dishwasher without the pump cover in place. Without it, the impeller spins in open water rather than channelling it through the pump outlet, so no drainage occurs at all. Running the motor against an unloaded impeller also risks overheating. The cover must be correctly seated before running any cycle.

How much does it cost to fix an E25 error?

Reseating the pump cover and clearing a jammed impeller costs nothing and resolves the error in the vast majority of cases. A replacement pump cover runs $10–$25 as a DIY part if the cover is cracked. A replacement drain pump motor runs $60–$100. Professional repair in the Boston area for pump clearing, cover replacement, or pump motor replacement typically runs $100–$280, parts and labor included.
