Checks to perform:
E51
E51: Motor Relay failure
E51
Motor Relay stuck open, locked rotor, harness, low power supply, Thermal Limit-
er – open, and Motor Centrifugal Switch -1 stuck open or closes.
WARNING
Check that all the connectors are correctly inserted
Turn ON the dryer and measure the continuity
between J2-1 and J2-2 Connectors of Electronic
Control Board. Is continuity there?
Replace the Electronic Control Board and repeat the
Diagnostic Cycle to check for any further alarms.
Measure resistance between the connectors J2
terminals of the Electronic Control Board and the
appliance body. (See Fig. 1) Is Resistance value not “0”?
Replace the Electronic Control Board and repeat the
Diagnostic Cycle to check for any further alarms.
Detach the connectors and measure between the
terminals (5, 4 & 3 ) of motor and the earth contact.
See Figures (2 and 3) Is Resistance value not “0”?
NO
Replace the Motor and repeat the Diagnostic Cycle to
check for any further alarms.
Replace the Motor and repeat the Diagnostic Cycle to
check for any further alarms.
Check Inlet Thermal Limiter for the continuity?
NO
Replace Inlet Thermal Limiter repeat the Diagnostic
Cycle to check for any further alarms.
