Panasonic Washing Machine H01 error code
The H01 error means your Panasonic washing machine detected a problem with the pressure sensor — the component that monitors the water level inside the drum. When this sensor develops a fault the machine cannot accurately control the amount of water it fills with and stops the cycle for safety. H codes on Panasonic washing machines generally indicate hardware faults that require professional attention. Unplug the machine and do not use it until it has been inspected.
