-Check the connections to the water heater. Are they loose? A build-up of corrosion around joints is a sure sign of a leak. (Non-Warranty)

-Check the seal around the air vent and drywell for leaks. Remove the drywell and check the O-ring gasket (if applicable) beneath it. (Non-Warranty) If they are leaking and it is not related to an installation error or system problem—*reason code 058.

-Remove the thermostat sensing bulb from the drywell. If the bulb wet or is water visible at the top of the drywell?—*reason code 059.

Action Item:

-To replace the drywell use the Replacement Kit. (See chart on Page 15, 17, 19 or 21)
