Safety comes first

If you smell gas, do not light an appliance, touch electrical switches or use a phone in the building. Call your gas supplier from a neighbor’s phone and follow the manual’s emergency instructions. Do not repair gas piping, the display, burners, vent connectors or safety devices. Refer repairs to qualified service personnel. Combustion problems, including vent blockage or inadequate gas pressure, require a qualified service technician.

Start with water, power and normal controls

Check whether the water shutoff is fully open, the unit has power and water supply, and the unit is ON. Open the hot water faucet fully: the manual notes that inadequate incoming water volume stops the burner. Note any displayed code and use the INW error reference.

Low temperature or a clogged filter

Check the temperature setting against the control guide and scald warnings. A clogged inlet filter is a listed cause: use the model’s isolated-power, closed-water filter procedure, or ask a qualified professional if you cannot follow it safely. A malfunctioning mixing valve needs professional attention, not homeowner replacement.

Frozen pipes and combustion problems

Do not use the appliance until frozen pipes have thawed. Vent blockage or insufficient gas pressure can trigger safety shutdown; contact a qualified service technician rather than adjusting gas pressure or altering venting.
