Bosch Dishwasher E25 Fault Code, Your Bosch Dishwasher Is Showing E25 — Here’s What To Check First
Your Bosch dishwasher is showing E25. The cycle has stopped, water is sitting in the bottom of the machine, and it won’t drain.
Here’s the thing most people get wrong: they assume the drain pump has failed and start looking at replacement machines. In reality, E25 can be caused by a blocked filter, a kinked hose, or a stuck check valve — all of which are free or cheap to fix.
The key is working out whether the fault is a blockage or the pump itself. The filter and hoses are free to check. The pump is the last thing to test.
This guide walks through the four most common E25 fault patterns in order: no drain at all, slow drain, drain then code returns, and E25 after moving the machine.
How E25 Differs From E24
Both are drain codes, and they can look similar. But the cause is usually different.
E24 usually means a blockage. The filter is clogged, the drain hose is kinked, or debris is blocking the water path. The pump is fine — it just can’t push water through the blockage.
E25 usually means the pump itself is faulty. The filter and hoses are clear, but the pump isn’t running properly or has debris inside it.
In practice: if the filter and hoses are clear and the pump runs but doesn’t pump, E25. If the filter is clogged or the hose is blocked, E24.
Common Symptoms
E25 with no drain at all
E25 with slow drain
E25 that clears then returns
E25 after moving the dishwasher
Water sitting in the bottom of the machine
The machine stops mid-cycle
What Causes These Faults
Blocked filter. The most common cause.
Blocked pump impeller. Debris inside the pump has jammed the impeller.
Failed drain pump. The pump motor has failed.
Blocked drain hose. The hose is blocked or kinked.
Blocked check valve. The check valve is stuck closed.
What the Guide Covers
This diagnostic guide walks through all four E25 fault patterns:
Drain pump testing with expected readings
Drain hose inspection and clearing
Check valve testing
Filter and sump inspection
Drain path testing
Full repair-or-bin framework
Each section includes a test procedure, what a good result looks like versus a failed one, and a repair-or-bin threshold.
What You’ll Learn
You’ll learn how to diagnose the fault from the symptom. No drain at all points to the filter or pump. Slow drain points to a partial blockage. Code returning points to debris in the pump.
You’ll learn how to clean the filter, check the pump impeller, test the drain pump with a multimeter, and check the check valve.
And you’ll learn how to decide whether a repair is worth doing or whether the machine has reached the end of its life.
Repair or Bin?
Most E25 faults are free or cheap to fix on dishwashers under six years old.
Cleaning the filter is free. A drain hose is $10 to $30. A check valve is $10 to $30. A drain pump is $30 to $80.
Where the maths changes is the sump or a machine with multiple faults. On a dishwasher over eight years old, the repair often isn’t worth doing.
The guide includes a full repair-or-bin framework, plus a DIY versus professional cost table.
Frequently Asked Questions
What does E25 mean on a Bosch dishwasher?
E25 means the machine has tried to drain and failed. It usually points to a drain pump fault or a blockage downstream of the pump.
How is E25 different from E24?
E24 is usually a blockage. E25 is usually the pump itself. But both can be caused by a clogged filter.
How do I reset E25 on a Bosch dishwasher?
Clean the filter, check the hoses, and run a test cycle.
Why does my Bosch dishwasher keep showing E25?
The underlying fault hasn’t been fixed. Check the pump and the drain path.
Can E25 be caused by a blocked filter?
Yes. A blocked filter can cause both E24 and E25.
Is it worth repairing a Bosch dishwasher showing E25?
Usually yes, if the fault is the filter, hose, or pump. If the machine is over 12 years old, replacement is usually the better call.

Bosch Dishwasher E25 Fault Code
Your Bosch Dishwasher Is Showing E25 — But It’s Usually Not the Control Board
Your Bosch dishwasher is showing E25. The cycle has stopped, water is sitting in the bottom of the machine, and it won’t drain.
Here’s the thing most people get wrong: they assume the drain pump has failed and start looking at replacement machines. In reality, E25 can be caused by a blocked filter, a kinked hose, or a stuck check valve — all of which are free or cheap to fix.
The key is working out whether the fault is a blockage or the pump itself. The filter and hoses are free to check. The pump is the last thing to test.
This guide walks through the four most common E25 fault patterns in detail: what causes each one, how to test for it, and when a repair makes sense versus when it’s time for a new machine. It also covers the drain pump testing, the check valve diagnosis, and the drain path inspection that the free post doesn’t.
Why Your Bosch Dishwasher Shows E25
E25 is a drain error code. The machine has tried to drain and failed.
The drain chain works like this: the control board signals the drain pump, the pump pushes water out of the sump, the water passes through the check valve, travels through the drain hose, and exits into the sink drain.
If any link in that chain fails, water can’t drain, and the machine shows E25.
Common Causes
Blocked filter. The most common cause.
Blocked pump impeller. Debris inside the pump has jammed the impeller.
Failed drain pump. The pump motor has failed.
Blocked drain hose. The hose is blocked or kinked.
Blocked check valve. The check valve is stuck closed.
Common Symptoms
E25 with no drain at all
E25 with slow drain
E25 that clears then returns
E25 after moving the dishwasher
Water sitting in the bottom of the machine
The machine stops mid-cycle
