Bosch Dishwasher E25 Error - Drain Pump or Blockage Warning
Bosch dishwasher E25 usually means the drain pump area may be blocked or unable to move water properly. Clean the accessible filter and pump-cover area only as the manual allows, check the drain route, and stop if E25 returns or the pump sounds jammed.
Quick answer
E25: The drain pump area may be blocked or unable to move water properly.
Meaning
The drain pump area may be blocked or unable to move water properly.
First safe check
Switch the dishwasher off and disconnect power before opening the filter or pump-cover area.
Stop if
Disconnect power first. Do not dismantle the pump, remove panels, bypass safety devices, or reach into areas where you cannot see debris clearly.
Who to call
Call a dishwasher engineer if E25 returns after safe filter and pump-cover checks, the pump is noisy or jammed, the impeller appears obstructed beyond safe access, water remains in the base, or the appliance would need to be opened.
Medium severity: check safely and stop if it returns. Disconnect power before checking accessible parts where the appliance guidance says to do so.
Fix time
10-25 minutes
Difficulty
Moderate if pump-cover access is awkward
The useful checks are the filter, visible sump or pump-cover area, hose route, and waste connection.
Expected outcome: Loose debris may clear after cleaning and one short test; repeat E25 suggests the pump path still needs diagnosis.
What does this error code mean?
Bosch dishwasher E25 usually means the dishwasher cannot drain because the pump area is blocked, restricted, or not moving water correctly. The fault is closely related to E24, but E25 more strongly suggests the pump-cover or pump path may be involved.
Food debris, labels, seeds, glass fragments, or a loose filter can restrict the pump area. Safe checks should stay inside the accessible filter and pump-cover area described in the model manual; do not dismantle the pump or remove side/base panels.
If the issue looks like a general drain restriction, compare Bosch dishwasher E24. If standing water is joined by a leak warning or water underneath, compare Bosch dishwasher E15 or Bosch dishwasher E30.
Symptoms users may notice
- The dishwasher may hum or grind during draining but leave water behind.
- E25 may appear near the end of the programme.
- Water may remain in the sump after the cycle stops.
- The filter or pump-cover area may contain food debris or small hard objects.
What users often notice
- E25 often appears after the dishwasher tries to drain and the pump cannot clear water normally.
- Users often report a pump noise, standing water, or E25 returning even after a basic reset.
Why is this happening?
- Debris around the accessible pump-cover area
- Blocked or incorrectly seated filter
- Food waste, labels, seeds, or glass fragments restricting the sump
- Restricted drain hose or blocked waste outlet
- Drain pump jammed or failing under load
What this usually points to
E25 usually points to the pump and drain route, especially the filter, pump-cover area, sump, drain hose, waste connection, and pump performance.
How to fix this safely
- Switch the dishwasher off and disconnect power before opening the filter or pump-cover area.
- Remove and clean the accessible filter, checking that it refits securely and sits flat.
- If your manual allows access to the pump cover, check only the visible area for loose debris and avoid sharp glass.
- Check the visible drain hose and sink waste connection for restrictions that could make the pump work against a blockage.
- Run one short drain or rinse test after refitting everything; stop if E25 returns, the pump grinds, or water remains in the base.
Can I fix this myself?
MaybeYou can safely clean the accessible filter and any user-accessible pump-cover area described in the manual. A noisy, jammed, or returning E25 fault should be treated as a repair issue.
Safety boundary: Disconnect power first. Do not dismantle the pump, remove panels, bypass safety devices, or reach into areas where you cannot see debris clearly.
What not to do
- Do not keep repeating resets if E25 comes back.
- Do not reach blindly into the pump area where glass may be present.
- Do not dismantle the pump or remove panels to chase the blockage.
Common misdiagnoses
- E25 can be treated as a simple reset issue, but repeated E25 usually means a real obstruction or pump-path problem remains.
- A visible filter clean does not rule out debris around the pump-cover area or a blocked waste connection.
Reset steps
- Refit the filter and pump cover exactly as the manual describes.
- Reconnect power only when the area is dry and there is no visible leak.
- Run one short drain or rinse programme to check whether water clears.
- Stop if E25 returns, the pump sounds jammed, or water remains in the dishwasher.
Intermittent vs persistent faults
A one-off E25 may clear after removing visible debris. Repeated E25 warnings should be treated as a persistent drain or pump-path problem.
When to call a technician
Call a dishwasher engineer if E25 returns after safe filter and pump-cover checks, the pump is noisy or jammed, the impeller appears obstructed beyond safe access, water remains in the base, or the appliance would need to be opened.
Safety warning
Disconnect the dishwasher from power before checking accessible filters or pump-cover areas. Do not dismantle the pump, remove panels, or work on internal electrical, pump, heater, or valve parts yourself.
