Seeing an F7 fault code on your Worcester Bosch Greenstar boiler? It usually points to an electrical / flame-detection-related fault — but the exact meaning varies by model, so always confirm it in your boiler’s manual and have gas-appliance faults diagnosed by a TSBC-licensed technician. ROMA Heating & Cooling repairs Worcester Bosch boilers across Greater Vancouver.
What the F7 code generally indicates
On many Worcester Bosch Greenstar models, an F7 is linked to the flame-sensing / electrical side of the boiler. A technician typically checks:
- Power supply and voltage to the boiler
- The flame-sense electrode, its wiring and position
- Earthing/grounding and connections
- The control board (PCB) and any related sensors
What you can do
Note the exact code shown, check your Worcester Bosch manual for its meaning on your model, and you can usually attempt a single reset. If the F7 returns, stop resetting and call a licensed technician — repeated resets on a gas appliance can be unsafe.
Safety first
If you ever smell gas or suspect carbon monoxide, leave the home and call your gas utility’s emergency line first. Never attempt internal gas, electrical or combustion repairs yourself.

Frequently Asked Questions
Is the Worcester Bosch F7 error serious?
It signals a fault the boiler has detected and locked out on. One reset is usually fine; if it returns, have it diagnosed — don’t keep resetting a gas appliance.
Can I fix an F7 error myself?
You can attempt one reset and check that power is on. The underlying electrical/flame-sensing fault should be diagnosed by a licensed technician.
