Ideal boiler error codes
18 codes from Ideal Heating. 5 of them are marked for a Gas Safe registered engineer; for the rest the page gives the checks 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 Ideal models can use different codes: your model’s manual is the authority.
