Common Dishwasher Problems — What They Mean

Most dishwasher problems have a straightforward cause. Here's what the most common faults mean and which ones need a professional repair.

Dishes coming out dirty

Check spray arm holes are clear, the filter is clean, and you're using enough detergent and rinse aid. If arms are clear but washing is still poor, the wash pump may be failing.

Machine not starting

Check the door is fully latched, the child lock isn't activated, and the power supply is working. A faulty door latch or control board can prevent the machine from starting.

Water sitting in the bottom

Indicates a blocked filter or failed drain pump. Clean the filter first. If water remains after a manual drain cycle, the pump likely needs replacement.

Error codes on the display

Error codes vary by brand. Common codes indicate water inlet issues (no water reaching the machine), drain faults, or overheating. Look up the code in your manual or call Go Assist for a diagnosis.

White film on glasses

Usually hard water deposits (limescale) or insufficient rinse aid. Top up the rinse aid reservoir and run a descaling cycle. Bournemouth and Poole have moderately hard water.
