How to fix a Toshiba HWS-1403XWHM3-E Heat Pump flow rate switch activation with error code A01?
- B
  Barbara NavarroSep 9, 2025
  If the flow rate switch is activated and you're seeing error code A01 on your Toshiba Heat Pump, it could be due to several reasons. First, there might be air in the pump; release the air completely according to the procedure. Low hydraulic pressure could also be the cause; set the hydraulic pressure considering pipe height, and replenish water until the manometer shows a value of set hydraulic pressure or more. Other potential issues include a clogged strainer (clean it), large resistance on the hydro side (widen the water path to the hydro unit or adopt a bypass valve), or a malfunction of the motorized 3-way valve for hot water supply (check the wiring and parts).

  If you're getting an E04 error, which indicates a regular communication error between the hydro unit and the outdoor unit of your Toshiba Heat Pump, check the serial circuit. Also, check for miswiring of the crossover between the water heat exchanger and the outdoor unit.
