    Why is my EemaX Water Heater producing low heat?
    • P
      Patricia ChenAug 20, 2025
      Low heat from your EemaX Water Heater can occur for several reasons: - The outlet temperature is below 90°F/32°C for 5 seconds of flow. - Element failure. - ECO tripped or malfunctioning. - Relay/contactor malfunctioning. - Control board failure. - Inlet water supply out of spec. To attempt a fix, reduce the flow through the unit.

    What to do if EemaX FlowCo SPEX3512 flow is too high?
    • S
      Shannon SummersAug 23, 2025
      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 causes residual heat in EemaX Water Heater?
    • D
      Deborah KingAug 30, 2025
      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 FlowCo SPEX3512 has over-temperature protection?
    • D
      Dustin WhiteSep 7, 2025
      If the outlet temperature of your EemaX Water Heater exceeds 130°F/54°C, it triggers over-temperature protection. To resolve this, increase the water flow through the unit. This will help decrease the overall temperature rise.
