E25 means the SHP78CM5N drain pump area is obstructed or its cover is not secured, so water cannot leave normally. Use the exact code to separate water inlet, drainage, foam, leak protection and internal faults. Do not order a part until the visible installation and removable filters have been checked. Glass, labels or food debris can jam the impeller, while a pump cover left unlocked lets pressure escape. Clean and lock the filter first. E25 with standing water and a clean filter directs attention to the pump cover and visible impeller area. Unplug, close water, let the sump cool, remove standing water and filters, then inspect the pump cover using cut-resistant gloves and remove only loose visible debris. Lock the cover and filter, then run cancel/drain. If the impeller resists or E25 returns, stop and use Bosch service.
Models covered
Safety first
- Wear gloves around the sump because broken glass may be hidden. Do not tilt a built-in appliance or remove its base, side panels or wiring cover.
What the symptom may indicate
Checks in the right order
- Confirm the pattern
Glass, labels or food debris can jam the impeller, while a pump cover left unlocked lets pressure escape.
- Prepare safely
Cancel the cycle, switch the dishwasher off, close the water valve and wait for hot water and dishes to cool before touching a filter or hose.
- Apply the official check
Unplug, close water, let the sump cool, remove standing water and filters, then inspect the pump cover using cut-resistant gloves and remove only loose visible debris.
- Retest once
Lock the cover and filter, then run cancel/drain. If the impeller resists or E25 returns, stop and use Bosch service.
Stop and get qualified help when
- Stop and arrange service for water in the base, a heat or motor code, a leak that continues with the valve closed, or a code that returns after one empty test.
Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
