WARNING
Check that all the connectors are correctly inserted
Check for the continuity between Motor Terminals (1 &
2). Is continuity there?
Replace the Motor and repeat the Diagnostic Cycle to
check for any further alarms.
Detach the connector from the Motor and measure the
resistance between terminal 5 & 4 Check Resistance
value are in between “2.6 Ω to 3.2 Ω” ? (See Fig.1)
NO
Replace the motor and repeat the Diagnostic Cycle to
check for any further alarms.
Replace the Heater and repeat the Diagnostic Cycle to
check for any further alarms.
Measure the resistance between the terminals of
Heating Element and check whether it is between 11 Ω
± 10% at room temperature (20-25°C) (See Fig.3)
NO
Replace the Heater and repeat the Diagnostic Cycle to
check for any further alarms.
Check Inlet Thermal Limiter for continuity.Is continuity
there?
Replace the Inlet Thermal Limiter and repeat the
