E18 or F18, not draining
Pump filter or drain hose blocked, or a worn drain pump.
Bosch washers, dishwashers, built-in ovens and hobs are found in many Nairobi kitchens. They are built to last and well worth repairing. We know their error codes and fit genuine Bosch parts.
Pick your Bosch appliance. Tell us what it’s doing and we’ll usually know the likely cause before we arrive.
Pump filter or drain hose blocked, or a worn drain pump.
Tap half closed, a blocked inlet filter or a failing inlet valve.
Water left in the drum, or a code like 5C, OE or E18. Usually a blocked filter, hose or a worn drain pump.
The anti-flood switch has tripped because water is in the base. We find the leak and dry it out.
A blocked filter, drain hose or something stuck under the pump cover.
Water left in the bottom from a blocked filter, drain hose or pump.
The fan element or the fan motor. We test both and replace the failed part.
A burnt-out element, thermostat or selector switch. On gas ovens, the igniter or valve.
A failed fan motor or fan element, or a thermostat reading the wrong temperature.
A cooling fan, power board or coil fault on Bosch induction hobs.
Blocked jets from spills, a wet or cracked igniter, or a faulty spark generator.
The spark is there but gas isn’t reaching the burner: jets, valve or supply.
Low gas from a leak, dusty condenser coils, a failed fan, thermostat or start relay.
We find and fix the leak first, then pull a vacuum and refill with the right gas for your fridge.
Frost on the back wall or around the fan points to a defrost heater, sensor or timer fault.
A blown thermal fuse, failed heater or thermostat.
A snapped drum belt or a worn motor or idler pulley.
Blocked lint filter, vent hose or condenser, or a weak heater.
A failed magnetron, high-voltage diode or capacitor.
A burnt waveguide cover or damaged cavity paint. Stop using it until it’s fixed.
A worn turntable motor or coupler.
For a Bosch dishwasher showing E15, don’t tip it to drain the base. Switch it off and call us: the leak that tripped the switch needs finding first.

Yes. E15 means water has collected in the base. We find the leak (often a seal, hose or sump), fix it and reset the anti-flood switch.
Almost always. Bosch washers, dishwashers and ovens are built well, and most faults are a pump, element, seal or sensor.
The diagnosis is free. The technician finds the fault on your Bosch washing machine, tells you the full price for parts and labour, and nothing starts until you approve it.
Most bookings in Nairobi and Kiambu get a same-day visit. Common Bosch parts travel in the van, so many repairs are finished on the first visit.
We fit genuine Bosch parts wherever they are available and tell you clearly when only a compatible part exists. Every repair carries our warranty.
No. HomeFixit is an independent repair company and is not affiliated with Bosch. If your Bosch appliance is still under the manufacturer’s warranty, contact the seller first; once it is out of warranty, we can help.
Three quick steps. We confirm your time on WhatsApp.
Free diagnosis, genuine parts and a warranty on every repair.
