These are the faults behind most calls for tankless water heater repair in Federal Way, WA. The display usually points at one of them.
Code 11, E003 or 111
A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.
Drip from the cabinet
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.
Code 10 or E110
Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
