The most common Bosch fault we see. Usually a blocked pump filter, failed drain pump, or blocked drain hose. Check and clean the filter first — it's accessible without an engineer and may save you a call-out.

Typically fixed in one visit

On older Bosch models carbon brush wear is a common cause — a cost-effective fix. On newer brushless motor machines more likely to be a control board or motor issue. Brushes carried as standard.

Brushes carried as standard

Drum not turning — can indicate a motor fault, worn brushes, or a seized drum. On Neff machines this code can present slightly differently. Needs proper diagnosis before parts are ordered.

Diagnosis required first

Machine not filling with water or filling too slowly. Usually a faulty inlet valve, low water pressure, or blocked inlet filter. Also check the tap is fully open before calling us out.

Check the tap first

Leak sensor triggered. Can be a genuine leak — door seal, dispenser hose, or pump — or a sensor fault. The dispenser hose is a common Bosch-specific cause of this code, and is often misdiagnosed.

Dispenser hose — common Bosch fault

Heating element failure causing the RCD to trip — usually moisture ingress or limescale damage to the element. Particularly common in hard water areas like Bath. Element needs replacing.

Elements carried as standard

Common on older machines used predominantly on cooler wash cycles. The rubber door gasket deteriorates over time, harbouring mould and eventually leaking. Straightforward replacement.

Seals stocked for most Bosch models

Bosch bearings are notably durable compared to budget brands — less frequently needed, but when a Bosch does develop a rumbling noise during spin, bearings are usually the cause. A bearing replacement is a significant job and in most cases replacement is the more economical option. We'll always give you an honest assessment.
