E25: Water Not Draining

Your Bosch dishwasher has displayed the E25 error code, which means water isn't draining away properly from the appliance. This typically indicates that either the drain pump is blocked or the filter assembly has become clogged with food debris and other particles. When water can't escape during the cycle, the dishwasher detects this problem and stops, displaying the error message on your control panel. Whilst this is rated as a high-severity fault, the good news is that many E25 errors can be resolved through simple DIY maintenance. In the majority of cases, the issue stems from a blocked filter or drain system rather than a faulty component requiring professional replacement. Food particles, grease buildup, or foreign objects can accumulate over time, restricting water flow. To diagnose and potentially fix this problem yourself, you'll need to inspect two key areas: the drain filter assembly and the drain pump. Both are accessible from inside your dishwasher and can often be cleaned without specialist tools. This guide will walk you through the diagnostic process, helping you identify whether you're dealing with a straightforward cleaning job or whether you need to contact a technician.

Many E25 faults can be resolved by a competent DIYer. Always disconnect from mains power first. If unsure, consult a qualified engineer.
