Common AO Smith geyser problems we fix
Water lukewarm or slow to heat
Scale on the element, or a thermostat cutting out early. We descale, test the thermostat under load, and replace only what has actually failed.
Anode rod finished
The magnesium rod protects the tank and wears out — on hard water faster than the book says. Replacing it on time is what keeps the tank from rusting; we check it at every service.
Safety valve releasing water
Line pressure or a failed valve. We check the inlet pressure first, because replacing a valve that was doing its job fixes nothing.
Error or no power on electronic models
On models with a display, a failed sensor or control board. Tested before replacement, and we say honestly when a board must come from the brand.

Parts and warranty
AO Smith elements, thermostats, anode rods and valves are available for current models. Some electronic parts are only supplied by AO Smith; where that is the case we tell you before quoting. Our work carries our own service warranty; parts carry the maker's.
HouseTech Care is an independent multi-brand service, not AO Smith's authorised service centre. We use genuine parts where the maker supplies them and say so when we cannot.
