Bosch washing machines we repair

Bosch front-load washing machines and washer-dryers, Serie 4, 6 and 8.

Faults we see on Bosch washing machines

Bosch washing machines commonly show E18 (will not drain: pump, filter or hose), F21 (drum not rotating correctly: motor, brushes or control), or an aquaStop water fault where the safety hose has triggered. The aquaStop inlet hose has electronics built into the connector and is replaced as a complete unit rather than repaired.

Bosch shares its platform with Siemens (both are made by BSH), so parts and the repair approach overlap heavily between the two brands.

How we approach a Bosch washing machine repair

A technician diagnoses the washing machine in person. Once the cause is confirmed, we check whether a genuine or approved compatible part is the right option for that model, and what it will cost, before anything is agreed.

Common Bosch washing machine fault patterns

E18 — not draining Pump filter, drain pump or blocked hose.
aquaStop triggered Safety hose has detected a leak; hose assembly and the leak source are addressed.
F21 — drum not rotating correctly Motor, carbon brushes or the control board, confirmed on site.

The actual cause is always confirmed by an on-site diagnosis before we quote.

Parts

Pumps, seals and aquaStop hoses are the parts most Bosch washing-machine repairs need; Serie 8 control boards may need ordering. We confirm availability, compatibility and cost for your specific model first.

We use genuine manufacturer parts when available and approved high-quality compatible parts when appropriate. The available options are explained before installation.

Bosch washing machine repair: common questions

Are you a Bosch authorised service centre?

Leadingfix is an independent repairer, experienced with Bosch appliances but not affiliated with or authorised by Bosch. If your Bosch appliance is under warranty, contact Bosch or your retailer first.

My Bosch washing machine's aquaStop hose has triggered. Is that serious?

It means the safety system has detected a leak and shut off the water. The hose is replaced as a unit and we find and fix the leak that triggered it — it does need a visit, but it's a contained repair.
