What to do if my EemaX LavAdvantage SPEX1812T Water Heater has no heat?
If your EemaX Water Heater isn't producing heat, the cause may be element failure, a tripped or malfunctioning ECO, failed open triac(s), a malfunctioning relay/contactor, control board failure, or an out-of-spec inlet water supply. You can measure element resistance with the unit completely turned off to troubleshoot.
What to do if EemaX Water Heater has undervoltage?
If your EemaX Water Heater is experiencing undervoltage, it indicates that the inlet voltage is too low compared to the heater's specifications. Provide voltage within specified range.
Why is my EemaX LavAdvantage SPEX1812T Water Heater producing low heat?
Low heat from your EemaX Water Heater can stem from undervoltage, failed open triac(s), control board failure, or inlet/outlet thermistor(s) failure. Verify the power supply (voltage) while the heater is running to address this issue.
What to do if EemaX LavAdvantage SPEX1812T flow is too high?
If the flow in your EemaX Water Heater is too high, preventing the water from heating to the setpoint temperature, reduce the flow. You can achieve this by using an outlet flow restrictor or a faucet aerator.
What to do if EemaX LavAdvantage SPEX1812T shows freeze warning?
If your EemaX Water Heater displays a freeze warning, it means the inlet temperature is too low (below 35°F). To resolve this, increase the temperature of the inlet water to meet product specifications.
What to do if EemaX LavAdvantage SPEX1812T Water Heater has overvoltage?
If your EemaX Water Heater is experiencing overvoltage, it means the inlet voltage is too high compared to the heater's specifications. Provide voltage within specified range.
What causes residual heat in EemaX LavAdvantage SPEX1812T?
Residual heat in your EemaX Water Heater, indicated by an elevated internal water temperature without flow, is caused by both triacs failing closed. To solve this, run water through the unit.
What to do if EemaX Water Heater has inlet thermistor failure?
If your EemaX Water Heater is showing an inlet thermistor failure, this is because the inlet thermistor is interrupted or disconnected. Inspect the connections/wiring of the inlet thermistor.
What to do if EemaX Water Heater has outlet thermistor failure?
If your EemaX Water Heater is showing an outlet thermistor failure, this is because the outlet thermistor is interrupted or disconnected. Inspect connections/wiring of outlet thermistor.
What to do if my EemaX Water Heater shows overvoltage?
If your EemaX Water Heater indicates overvoltage, it means the inlet voltage is too high compared to the heater's specifications. Have certified personnel check the inlet voltage and ensure it's within the specified range.
