E25 on a Bosch dishwasher means the drain pump area has a problem – a blockage, a jammed impeller, or a pump cover that's worked itself loose. The machine stops, the code appears, and there's often water sitting in the bottom of the tub.
It's one of the more fixable Bosch fault codes. Most E25 errors clear after a filter clean and a pump cover check, without any parts replacement involved.
National Appliance Repairs diagnoses and repairs Bosch dishwashers across Australia. When the DIY steps don't clear it, our technicians carry the parts and diagnostic tools to finish the job in one visit.
What Causes the Bosch Dishwasher E25 Error?
Bosch officially describes E25 as a blocked drain pump or loose/missing drain pump cover. In practice, a few related issues can trigger the same code:
| Cause | Likelihood | DIY Fix? |
|---|---|---|
| Jammed pump impeller (glass, seed, label) | Very common | Yes |
| Drain pump cover loose or unseated | Very common | Yes |
| Blocked or dirty filter | Common | Yes |
| Kinked drain hose | Moderate | Yes |
| Failed drain pump motor | Less common | No |
| Damaged internal check valve | Uncommon | No |
E25 is a pump-area code, but a badly blocked filter can produce the same symptoms. Always check the filter first – it takes two minutes and solves more E25 faults than people expect.
Cut power at the wall before you start. Water in the tub may still be hot after an interrupted cycle. Give it 20–30 minutes before reaching into the sump.
Step 1: Remove the Filter and Check the Sump
Pull the lower rack out and twist the filter cap counterclockwise to release it. Rinse the assembly under hot running water until it's clear of grease and food residue.
With the filter removed, look into the sump below it. Small debris – glass, pips, foil seals – collects here and jams the impeller from below. It's not always visible; run a gloved finger around the sump floor to catch anything that isn't obvious to the eye. Clear it out fully before moving to the pump cover.
Step 2: Inspect and Reseat the Pump Cover
With the filter removed, the drain pump cover is visible at the bottom of the sump. On most Bosch models it's a round plastic disc that clips into place.
- Check whether the cover is sitting flush and correctly seated. A cover that's even slightly dislodged will trigger E25.
- If it's loose, use the handle of a teaspoon to gently pry the cover off – it usually unclips with light pressure.
- Inspect underneath the cover for any foreign objects resting on or around the pump impeller.
- Wearing protective gloves, feel around the impeller area – broken glass is a common find and isn't always visible.
- Clear any debris, then press the pump cover firmly back into place until it clicks audibly.
Step 3: Check the Drain Hose
Trace the hose from the machine to the sink drain and feel along it for kinks or flattened sections. The outlet needs a high loop – up toward bench height, then down to the drain connection – to prevent back-siphoning when the pump stops. If the hose looks suspect, pull it off at the drain end and flush water through it before reconnecting.
Step 4: Run a Test Cycle
Reassemble the filter, replace the lower rack, and run a quick or rinse programme. These short cycles reach the drain phase within a few minutes, so you'll know quickly whether the fix has held. No E25 means the problem is resolved.
When the Pump Itself Has Failed
If every previous check comes back clear and E25 keeps appearing, the pump motor or check valve has failed. Listen for grinding or clicking during the drain phase, watch for a pump that runs without shifting water, and note whether the code lands at the same point each time – all three are reliable indicators. Replacing the pump means partial disassembly and working with electrical connections. Get a technician to confirm failure first; it's a straightforward diagnosis with the right equipment and saves ordering parts blind.
Frequently Asked Questions
What does E25 mean on a Bosch dishwasher?
E25 means the drain pump is blocked, the pump cover is loose or unseated, or a foreign object is preventing the pump impeller from spinning. It's a drain-area fault that often resolves after clearing debris and reseating the pump cover.
How do I fix the E25 error on my Bosch dishwasher?
Remove the lower rack, unscrew the filter, and inspect the sump for foreign objects. Check whether the drain pump cover is seated correctly – it should click into place. Clear any debris, reseat the cover, reinstall the filter, and run a short cycle to test.
Is E25 serious on a Bosch dishwasher?
E25 isn't inherently serious, but it shouldn't be ignored. Running the dishwasher with standing water repeatedly can damage the pump motor over time and lead to odours and poor wash results.
What's the difference between E22 and E25 on a Bosch dishwasher?
E22 is a filter fault, indicating the filter needs cleaning. E25 is a pump-area fault, pointing to a blockage in the pump, a loose pump cover, or a failed pump motor. Both involve drainage but at different points in the system.
How do I prevent the E25 error?
Clean the dishwasher filter after every heavy wash cycle or at least once a week. Pre-scrape plates before loading to keep large debris out of the sump. Avoid washing items with loose labels, seeds, or small bones that can reach the pump area.
Book a Technician If Needed
Clearing the pump and filter resolves most E25 faults, but when the pump itself has failed or the check valve is damaged, professional diagnosis saves time and prevents guesswork. National Appliance Repairs services Bosch dishwashers across Melbourne, Sydney, Brisbane, Adelaide, and Perth – with same-day availability in most metro areas and a 12-month warranty on parts.
