5 FLASH CYCLE – THERMISTOR SHORT CIRCUIT Display pattern: 5 flashes then a short pause - repeated. Electronic check: This indicates that the Thermistor is measuring zero resistance. It assumes the thermistor has failed sort circuit. The element and inlet valve are turned OFF when this error is detected ...
4.7. Tank Components The tank internals are detailed below. Care should be taken when cleaning inside the tank. The level probes provide much of the control inputs into the PCB and are critical to the operation of the machine. The wiring to these should be checked regularly and the probes themselves should be cleaned whenever the machine is serviced.
