What to do if my Atmor 900 Water Heater has no hot water?
- NNicholas BennettJul 31, 2025
If your Atmor Water Heater isn't producing hot water despite the faucet being fully open, several factors could be at play. First, check the circuit breaker and voltage at the wiring block to ensure there's electrical power. Low voltage could also be the culprit; use a voltage meter to compare the reading at the heater's outside terminals against the specified voltage in the installation instructions. Also, the heater should be mounted no more than 12-18 inches from the point of use. Finally, controlling the flow rate is essential to ensure proper temperature increase, so check your flow rate to ensure proper operation of the heater.
