Tub full of water
The door stays locked or opens to a drum with standing water, and the cycle never finishes.
Start here: Start with safe water removal, then open and clean the washer drain filter and inspect the pump cavity.
Washer error code troubleshooting
Bosch Washer E25 F25 Error
Direct answer: A Bosch washer E25 or F25 error usually means the machine is not draining the way it should. Most of the time the fix is a blocked drain filter, debris jammed in the washer drain pump, or a kinked washer drain hose.
Most likely: Start with standing water in the drum, then check the drain filter and pump cavity for lint, coins, hair pins, or small clothing items.
If the tub is still full of water and the cycle stopped, treat this like a drain-path problem until proven otherwise. Reality check: a single coin or baby sock can stop a washer cold. Common wrong move: forcing another cycle without clearing the water first can leave you with more water on the floor and no better answer.
Don’t start with: Do not start by ordering an electronic part. On this code, a plain blockage is more common than a failed control or sensor.
If the drum is full of water,go straight to the filter and pump cleanout before trying another cycle.
If the washer drains but still throws the code,look harder at a weak washer drain pump or a partially blocked hose path.

What this code usually looks like in the house
Humming or buzzing at the bottom front
You hear the pump try to run, but little or no water leaves the washer.
Start here: Check for a jammed washer drain pump impeller or a clog right at the filter housing.
Drains slowly, then errors out
Some water leaves, but the machine times out and throws E25 or F25 before the tub fully empties.
Start here: Look for a partial blockage in the washer drain hose, standpipe connection, or pump outlet path.
No standing water, but code returns
The washer seems mostly empty, yet the code comes back on drain or spin.
Start here: Recheck for debris around the pump impeller and consider a weak washer drain pump if flow is still poor.
Most likely causes
1. Blocked washer drain filter
This is the most common cause. Lint, hair, coins, and small fabric pieces choke flow and make the washer think it cannot drain in time.
Quick check: Open the lower access area, drain the water slowly, and inspect the filter for packed debris.
2. Debris jammed in the washer drain pump impeller
A pump can hum and still not move water if the impeller is jammed by a coin, pin, rubber band, or string.
Quick check: With power disconnected and the filter removed, feel for debris in the pump cavity and see whether the impeller is blocked.
3. Kinked or partially clogged washer drain hose
If the filter is clean but the washer still drains slowly, the restriction is often farther downstream in the hose path.
Quick check: Pull the washer forward enough to inspect the full drain hose for sharp bends, crushing, or lint sludge at the standpipe end.
4. Weak or failing washer drain pump
When the filter and hose are clear but the pump only hums, drains very slowly, or quits hot, the pump itself becomes the likely fix.
Quick check: Run a drain cycle after clearing blockages. If flow is still weak or inconsistent, the washer drain pump is suspect.
Step-by-step fix
Step 1: Confirm whether this is a real drain problem
These codes are most useful when you match them to what the washer is physically doing. Standing water and pump noise tell you where to start.
- Cancel the cycle and unplug the washer.
- Look through the door glass or open the door only if it is safe and unlocked.
- Check whether there is standing water in the drum, damp clothes with no spin, or a strong humming sound from the lower front area.
- If the washer is empty and acting normal otherwise, note when the code appears: during drain, spin, or right after rinse.
Next move: You have a clear starting point: full tub means blockage first, while an empty tub with repeat drain faults points to weak flow or pump trouble. If you cannot tell whether water is still inside, assume there is some water present and prepare for a controlled drain at the filter area.
What to conclude: This keeps you from chasing the wrong problem. On this code, visible water and slow drain clues matter more than the display alone.
Stop if:
- You smell burning insulation or see signs of overheating near the lower front panel.
- Water is already leaking onto the floor and you cannot control it with towels and a shallow pan.
Step 2: Drain the washer safely and clean the washer drain filter
A blocked filter is the fastest, safest, and most common fix for E25 or F25.
- Place towels and a shallow pan at the lower access area.
- Open the service door or lower access panel.
- If there is an emergency drain tube, drain water into the pan a little at a time. If there is no tube, loosen the filter cap slowly and control the flow.
- Remove the washer drain filter completely.
- Clean off lint, hair, coins, buttons, and sludge with warm water and mild soap if needed.
- Look into the filter housing with a flashlight and remove any loose debris you can reach safely.
Next move: If the filter was packed and the washer drains normally on the next test, you likely found the problem. If the filter was fairly clean or the code returns, move to the pump cavity and hose checks.
What to conclude: A dirty filter can stop flow by itself, but a clean filter with the same code usually means the blockage is deeper or the pump is weak.
Step 3: Check the washer drain pump cavity for a jam
Small hard items often slip past the filter opening and wedge the impeller so the pump hums without moving much water.
- Keep the washer unplugged and the filter removed.
- Use a flashlight to inspect the pump cavity behind the filter opening.
- Look for coins, pins, rubber bands, strings, pet hair clumps, or a small sock edge caught near the impeller.
- Gently move the impeller with a fingertip if you can reach it safely. It should not be frozen solid by debris.
- Remove loose obstructions carefully without prying hard on the impeller blades.
Next move: If you remove debris and the impeller turns freely, reinstall the filter and test a drain or rinse-and-spin cycle. If the impeller is damaged, wobbly, or still barely moves with the cavity clear, the washer drain pump is the likely repair.
Step 4: Inspect the washer drain hose and standpipe connection
If the pump area is clear but the washer still drains slowly, the restriction is often in the hose path behind the machine.
- Pull the washer forward carefully without straining the water hoses or power cord.
- Inspect the washer drain hose from the back of the washer to the standpipe or sink connection.
- Straighten any sharp kinks and look for crushed spots behind the cabinet.
- Remove the hose from the standpipe or drain connection if you can do it without making a mess.
- Check the hose end for lint buildup or sludge and rinse it clear with water.
- Make sure the hose is reinstalled securely and not shoved so far into the standpipe that it restricts flow.
Next move: If you find a kink or clog and the washer drains strongly afterward, the hose path was the problem. If the hose path is clear and the washer still throws the code, the pump is the strongest remaining suspect.
Step 5: Test one clean drain cycle and decide on the repair
After the easy blockages are cleared, one controlled test tells you whether you are done or whether the washer drain pump has earned replacement.
- Reinstall the washer drain filter snugly by hand.
- Restore power and run a drain, rinse-and-spin, or short cycle with no laundry inside.
- Listen for the pump: a healthy pump sounds steady and moves water out with a strong, continuous flow.
- Watch the drain hose discharge if visible.
- If the washer still drains weakly, hums, or throws E25 or F25 again after the filter, pump cavity, and hose are clear, replace the washer drain pump.
- If the hose itself is damaged or leaking, replace the washer drain hose before using the washer again.
A good result: If the washer drains fully and the code stays gone, put it back in service and keep an eye on the next few loads.
If not: If the code returns with a clear drain path and weak pump performance, stop chasing it and replace the washer drain pump or book service if access is beyond your comfort level.
What to conclude: At this point you have ruled out the common clog spots. Repeat failure now points to a real component problem, most often the washer drain pump.

FAQ
Is Bosch washer E25 the same kind of problem as F25?
For homeowner troubleshooting, treat both as a drain-path problem first. Start with standing water, the washer drain filter, the pump cavity, and the drain hose before assuming an electronic failure.
Can a clogged filter really stop the whole washer?
Yes. A packed washer drain filter can slow flow enough that the machine times out and stops the cycle. That is why the filter is the first place to look.
My washer hums but will not drain. Is the pump bad?
Maybe, but not automatically. A humming pump often means the impeller is jammed by debris. Clear the filter and inspect the pump cavity first. If the path is clear and flow is still weak, then the washer drain pump is the likely fix.
Why did the code come back right after I cleaned the filter?
Usually because debris is still in the pump cavity, the washer drain hose is partially blocked, or the pump is weak and only worked a little better for one cycle. Recheck the whole drain path before buying parts.
Can I keep using the washer if it eventually drains?
It is better not to. Slow draining usually gets worse, and repeated stalled cycles can leave water sitting in the tub, stress the pump, and create a bigger mess when the washer stops completely.
Do I need to replace the control board for this code?
Not as a first move. On this symptom, a blockage or weak washer drain pump is far more believable than a control problem. Save board-level diagnosis for after the drain path has been proven clear and the pump has been tested by behavior.
