    Why is my Toshiba HWS-1403XWHT6-E Heat Pump not heating or cooling properly?
    • A
      Anna RiveraAug 19, 2025
      There are several reasons why your Toshiba Heat Pump might not be heating or cooling effectively. It could be due to an incorrect remote controller setting, so check your operation and temperature settings. An incorrect function code setting could also be the cause; verify the function code setting using the function code table. Other potential issues include a disconnected backup heater (check the heater and bimetal thermostat), insufficient capacity (check the equipment selection), or a sensor defect (ensure the temperature sensor is correctly positioned).

      Your Toshiba Heat Pump might not be cooling or heating because a scheduled operation is set. Please check whether scheduled operation is set. Also, check the remote controller to see if night setback operation is enabled. If the air to water heat pump is operating in Auto mode, the target value is set automatically according to the outdoor unit temperature. Note that the Auto mode can be adjusted, but you should contact the installation company for assistance.

      Ryan ChapmanAug 25, 2025
      If nothing is displayed on your Toshiba Heat Pump remote controller, the issue could be that power is not being supplied. Check the power supply wiring. Alternatively, there might be an incorrect setting; check the DIP switch setting on the Hydro Unit board and compare it with the function code table.

    What to do if my Toshiba Heat Pump is not supplying hot water?
    • K
      karenbrownAug 28, 2025
      If your Toshiba Heat Pump isn't supplying hot water, first check if the main water supply cock is closed and ensure the valves are open. Also, consider whether you are using too much hot water; if you use hot water exceeding the storage capacity, water at a temperature lower than the set hot water temperature will be supplied.

    What to do if hot water leaks from the Toshiba HWS-1403XWHT6-E pressure relief valve?
    • K
      Kenneth SweeneySep 7, 2025
      If hot water is leaking from the pressure relief valve of your Toshiba Heat Pump, it could be due to excessive hydraulic pressure. Set the hydraulic pressure considering the pipe height, and replenish water until the manometer shows a value of set hydraulic pressure or more. Another cause might be insufficient capacity of the expansion tank; check its capacity compared to the total water amount, and install another expansion tank if needed. Finally, the expansion tank might have failed, so check the air pressure.
