Bosch Washer Error Code E25 – Drain Pump Blocked (Denver Troubleshooting Guide)
Denver homeowners frequently experience the E25 drain error, often due to hard-water mineral buildup combined with lint or debris blocking the pump filter or hose. If your washer leaves water in the drum or won’t drain, this is the most likely cause.
Why E25 happens in Denver:
• Mineral deposits restricting pump movement
• Clogged filter from lint & coins
• Drain hose blockage from detergent residue
• Pump impeller stuck or damaged
Warning signs:
• Smell from stagnant water
• Loud buzzing during drain cycle
• Repeated drain failure
If cleaning the filter and hose doesn’t fix the issue, the pump may need replacement.
