Page 136: Maintenance
Maintenance Maintenance Preventive maintenance has been reduced to a minimum by the careful design of reliable components and material. However, the following measures should be taken at regular intervals and in proportion to the hours of service. Make certain that all electrical power to the machine is shut off before removing top or rear panels.
Page 137 Maintenance Weekly • Remove hose from drain connection and clean inside drain valve. Every three months • Remove the cover plates of the machine and Fig. check that the V-belt of the motor is undamaged and correctly tensioned. • Check that all tubing, piping and connections are free from leaks.
Page 138: Trouble-Shooting
Trouble-shooting The purpose of the trouble-shooting guide is to facilitate the location an 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 on the control panel should be moved in and out in order to eliminate improper contact due to faulty connection.
Page 139 Trouble-shooting If machine does not start Fig. A Check circuit breaker in the power feed line to the machine. B Check door safety switches. C Check glass cartridge fuse. E Check for fault indication on display (see under the heading ''Fault finding'').' If water does not drain A Check for fault indication on display (see Fig.
Page 140 Trouble-shooting If machine does not extract A Check for fault indication on display (see under Fig. the heading ''Fault finding''). If motor does not operate at wash speed. A Check for fault indication on display (see under Fig. the heading ''Fault finding''). B Check motor and V-belts.
Page 141 Trouble-shooting If machine runs slowly on wash speed or there is a slapping or thumping noise: Fig. Replace V-belts. If a metallic noise can be heard at rear of machine: Fig. Tighten pulley on motor shaft. If the door is leaking: Check door gasket.
Page 142 Trouble-shooting If there is leaking around the glass. Fig. A Re-cement glass in door gasket, if worn. B Replace door gasket if worn. If water does not enter the machine. Fig. A Check the valve coils on inlet valves. B Check wires leading to electric coils. C Be sure manual shut-off valves are in open position.
Page 143 Trouble-shooting If water continues to fill without stopping. A Check for incorrect programming. B Check hose attached to level control unit on the printed circuit board. C Check inlet valves for dirt underneath the valve diaphragm. To localize, shut off power. If water continues to flow, inlet valves have foreign material in them and should be thoroughly cleaned.
