  If your Toshiba Heat Pump isn't heating or cooling the room adequately, or the water isn't hot enough, there might be several reasons: * The remote controller settings may be incorrect. Check the operation and temperature settings. * The function code setting could be wrong. Verify it using the function code table. * The backup heater might be disconnected. Inspect the backup heater and bimetal thermostat. * The unit might have insufficient capacity. Review the equipment selection. * A temperature sensor may be defective or not properly positioned.

What to do if my Toshiba Heat Pump has almost no or little water flow and shows error code [A01]?
- J
  Jennifer RochaAug 21, 2025
  If your Toshiba Heat Pump exhibits little to no water flow and displays error code [A01], consider the following: * There may be an air bite in the pump. Release the air completely, following the correct procedure. * The hydraulic pressure may be low. Set the hydraulic pressure appropriately, considering the pipe height, and replenish water until the manometer shows the set hydraulic pressure or more. * The strainer might be clogged. Clean the strainer. * There could be large resistance on the hydro side. Widen the water path to the Hydro Unit or adopt a bypass valve. * The motorized 3-way valve for hot water supply might be malfunctioning. Check the wiring and parts.

Why is hot water leaking from the overpressure preventive valve of my Toshiba Heat Pump?
- S
  Sarah KellyAug 28, 2025
  Hot water leaking from the overpressure preventive valve of your Toshiba Heat Pump can be due to: * Excessive hydraulic pressure. Set the hydraulic pressure considering pipe height and replenish water until the manometer shows a value of set hydraulic pressure or more. * Insufficient capacity of the expansion tank. Check the expansion tank capacity compared to the total water amount; if it's insufficient, install another expansion tank. * Expansion tank failure. Check the air pressure.
