Siemens
Sister brand to Bosch, built on the same platforms, so faults, parts and error codes are closely related. Typical repair cost for a Siemens dishwasher: £70–£170.
Siemens shares the Bosch fault code system: E18, E17, F21 and F23 on washers and E15, E24, E25 on dishwashers.
Most Siemens dishwasher repairs cost £70–£170 including parts and labour. Prices depend on the fault and parts availability.
Pump, filter, seal, spray arm and heater repairs are usually well worth doing on machines under 8 years old. Replace if the control module has failed on an older budget model, or the tub is rusted or cracked.
The model and serial number are on a rating plate — typically inside the door frame, on the back panel, or inside the fridge on the side wall. Quote it when booking a repair so the engineer brings the right parts.
