Potterton boiler error codes
15 codes from Potterton (Baxi Heating UK). Every one comes with a check the maker lets an owner do. Tap a code for its meaning:
Gas boiler: do only the checks its user manual gives you — read the pressure gauge, top up through the filling loop, press the reset button, thaw a frozen condensate pipe at ground level. Keep the casing on and leave sealed parts alone. Anything else is for a Gas Safe registered engineer. If you smell gas, call the National Gas Emergency Service on 0800 111 999. Two Potterton models can use different codes: your model’s manual is the authority.
