Why is my Toshiba Heat Pump not heating or cooling properly?
- J
  Jeremy FreemanAug 13, 2025
  There are several reasons why your Toshiba Heat Pump might not be heating or cooling effectively. It could be due to an incorrect setting on the remote controller. Make sure to check the remote controller operation and temperature settings. It may also be due to an incorrect function code setting. Refer to the function code table to verify the settings. Another possible cause is a disconnected backup heater, so you should inspect the backup heater and bimetal thermostat. Insufficient capacity of the heat pump itself or a defect with the temperature sensor could also be factors. Check the equipment selection and ensure the temperature sensor is installed correctly.

  There might be several reasons why your Toshiba Heat Pump isn't cooling or heating the room: * Check if the scheduled operation is set, as this could be affecting the temperature. * Verify the settings on the remote controller to ensure night setback operation isn't active. * If the air conditioner is in Auto mode, the target temperature is automatically set based on the outdoor unit temperature. Note that the Auto mode can be adjusted by contacting the installation company.

  Timothy DavisAug 25, 2025
  If your Toshiba Heat Pump isn't supplying hot water, consider the following: * Ensure that the main water supply cock is open and check all valves. * Be mindful of hot water usage. If you use hot water exceeding the storage capacity, the supplied water temperature will be lower than the set temperature.

What to do if hot water leaks from the pressure relief valve of my Toshiba HWS-1402XWHT9-E Heat Pump?

  melissa77Sep 5, 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 an insufficient capacity of the expansion tank compared to the total water amount, in which case you should consider installing another expansion tank. A failure of the expansion tank itself could also be the reason; check the air pressure.

How to fix the error code [P01] on my Toshiba Heat Pump due to flow rate switch activation?
- H
  Haley BennettSep 9, 2025
  If your Toshiba Heat Pump displays error code [P01] and the flow rate switch is activated, it could be due to several reasons. First, there might be air trapped in the pump; release the air completely according to the proper procedure. Low hydraulic pressure could also trigger this error; set the hydraulic pressure considering the pipe height, and replenish water until the manometer shows a value of set hydraulic pressure or more. A clogged strainer, large resistance on the hydro side, or a malfunction of the motorized 3-way valve for hot water supply could also be the cause. Clean the strainer, widen the water path to the hydro unit or adopt a bypass valve, and check the wiring and parts of the 3-way valve.
