Replacing Parts
Before removing and replacing any part on the appliance the appliance must be isolated from the
water and electricity supply.
Replacement of parts must be parts approved by the manufacturer.
Thermostat
• Remove the outer lid.
• Remove the retaining screws from the back panel and slide the back panel vertically upward.
• Remove the retaining screws from the access panel.
• Loosen the thermostat gland and withdraw the thermostat bulb through the union.
• Remove the wires from the thermostat terminals, noting the connections.
• Loosen the thermostat retaining screws and remove the thermostat.
• Fit the new thermostat and assemble in reverse order.
• Electrically test the appliance.
Contactor
• Remove the retaining screws from the access panel.
• Remove the wires from the contactor terminals, noting the connections.
• Spring the contactor-retaining clip to free the contactor from the bracket.
• Fit the new contactor, ensuring the contactor is fully seated on the bracket, and assemble in
reverse order.
• Electrically test the appliance.
Solenoid
• Drain the tank as described earlier in the de-scaling routine.
• Remove the retaining screws from the access panel.
• Loosen the solenoid retaining screws.
• Loosen the pipe clip.
• Remove the wires from the solenoid terminals, noting the connections.
• Withdraw the solenoid. There may be a small quantity of water remaining in the hose.
• Fit the new solenoid and assemble in reverse order.
• Electrically test the appliance.
Circuit Board
• Remove the outer lid.
• Remove the retaining screws from the back panel and slide the back panel vertically upward.
• Remove the retaining screws from the access panel.
• Remove the wires from the solenoid, contactor/thermostat, neon, terminal block, and element,
upper and lower sensors. Note: To free the wires from the neon, loosen the tank-retaining
bracket and ease that tank backward to gain access to the neon housing.
• Free the circuit board from the mounting clips.
• Fit the new circuit board and assemble in reverse order. Attention must be given to the wiring
on the level sensors.
• Electrically test the appliance.
