Trouble shooting
The purpose of the trouble shooting guide is to facilitate the location and
correction of the most common machine problems.
Before the top panel is removed, power to the machine is to be switched off at
the main source or at the separate circuit breaker.
At each trouble shooting attempt, the plug in connectors of the control panel
should be moved in and out in order to eliminate improper contact due to faulty
connection.
Please note that this guide does not include all possibilities, but only those most
likely to cause the symptoms listed.
In trouble-shooting electrical problems, always make certain to have the proper
electrical schematic or wiring diagram at hand. Test for power using a V-O-M or
similar meter on the AC voltage scale. Test for continuity with all electrical power
off.
If machine does not start
A Check the circuit breaker in the power feed line to the machine.
B Check the door safety switches.
C Check the glass cartridge fuse.
D Check the normally closed auxiliary contact on the extract relay.
E Check reversing switch.
F Check the V-belt and motor.
G Check programmer switch M.
H Check the start switch on the side of the programmer.
If water does not drain
A Check the drain valve and motor and gearing for proper operation.
B Disconnect drain hose connected to drain line. If full flow of water comes out,
the problem is in the main waste line. If water flow is slow, the problem is the
accumulation of foreign materials between the drain valve and drum outlet of
machine.
C Clean valve body for any foreign objects.
D Check program switch K.
E Check the drain relay.
If machine does not extract
A Check extract relay and relay coil for proper operation.
B Check programmer switches H and/or L
C Check the extract safety level control.
D Check the reversing switch.
E Check the door lock.
F Check all the drain items of ''If water does not drain''.
