Re: SmartDrive 503 error Code 1101
‘Ello,
Problem with the pressure switch (water level control) system. The switch is sending a negative signal to the computer, instead of a positve one. Basic steps to take:
Drain all the water from the machine. Remove air hose from pressure switch – blow through and clear any water which may have entered. Check condition of air hose for pinholes, kinks, trapping etc. If the machine continues to bring up the fault, the pressure switch itself may be faulty. It is integral with the computer board, so a fairly expensive replacement if this is the case.
Stay safe, pull the plug.
