  • Page 34 Mechanical and electrical design Relays The W-series models employ either two Fig. (W75, 105) or three (W125, 185) relays to energize the windings of the wash/extract motor. The relays control: • The reversing action of the motor at wash speed. •...
  • Page 35 The trip level for any one pressure switch can be changed only within narrow limits because each trip range requires a different set of springs. Call Wascomat's Service Department at 516-371-0700 before attempting to adjust the level control. Water level As a guide for checking the level control for proper functioning, the normal level should be approximately at the bottom of the door glass.

  • Page 42: Maintenance

    Mechanical and electrical design Maintenance instructions Limescale can block the hole in the valve diaph- ragm and interfere with the function of the valve. It is therefore advisable to dismantle and clean Fig. the valve at certain regular intervals. The fre- quency depends on operating conditions and the level of contamination in the water.
  • Page 43 Mechanical and electrical design Inlet valve for W185 from S/N 9508/011935 The water inlets have brass bodies with larger Fig. cross section of the outlet in order to achieve a shorter filling time for the machine.

  • Page 47 Maintenance Maintenance Preventive maintenance has been reduced to a minimum by the careful design of reliable compo- nents and material. However, the following measures should be taken at regular intervals and in proportion to the hours of service. IMPORTANT! Make certain that all electrical power to the machine is shut off before removing top or rear panels.
  • Page 48 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 must be switched off at the main source or at the separete 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 49 Trouble shooting Trouble shooting If the machine does not start A Check the circuit breaker in the electrical Fig. power line to the machine. B Check the door safety switch and door lock. C Check the glass cartridge fuses. D Check for loose wires at the incoming power terminal block.
  • Page 50 Trouble shooting If the machine does not extract Fig. A Check the extract relay and relay coil for proper operation. If the motor does not operate at wash speed A Check the wash relay(s). Fig. B Check the normally-closed contact of the extract relay.
  • Page 51 Trouble shooting If the machine runs slowly on wash speed or there is a slapping or thumping noise. Fig. A Replace the V-belts If a metallic noise can be heard at rear of machine Fig. A Tighten the pulley on the motor shaft If the door is leaking A Check the door gasket.
  • Page 52 Trouble shooting If there is a leaking around the glass Fig. A Replace the door gasket if worn. If water does not enter the machine. A Check the valve coils on the inlet valves. Fig. B Check wires leading to the valve coils. C Be sure manual shut-off valves are in open position.
  • Page 53 Trouble shooting If water continues to fill without stopping. A Check the hose attached to the level control Fig. unit. B Check inlet valves for dirt underneath the valve diaphragm. To isolate the cause, shut off power. If water continues to flow, inlet valves have foreign material in them and should be thoroughly cleaned.
  • Page 54 Trouble shooting If the machine vibrates excessively. Tighten the mounting bolts. Fig. Check that the shipping security has been removed. Refer to Function control on page 1140...
