Troubleshooting
Combi Boiler Tripping the Electrics
An electrical trip is a safety signal — don't keep resetting it.
Licensed & Insured Gas-Certified Technicians Serving Vancouver Since 1999
A combi boiler that trips your breaker or RCD is signalling an electrical fault — often moisture ingress, a failed pump or fan winding, or a damaged heating element or PCB. Repeatedly resetting the breaker is unsafe.
This needs prompt diagnosis by a qualified technician; leave the breaker off if it keeps tripping.
Common causes
- Water ingress into electrical components
- Failed pump or fan motor winding
- Damaged wiring or connector
- Faulty control board
- Shared-circuit overload
