4.5Water Valves

The electronics control the water valves so that a constant water temperature is achieved in the bowl irrespective of the temperatures and pressures of the household hot and cold water systems. To achieve accurate water temperatures a proportional water valve is used on the cold water inlet. Unlike conventional water valves which are either fully on or fully off, the proportional water valve can be controlled so that it can turn on at any water flow rate between fully on and fully off.

	Proportional Valve	Standard Valve
Filter colour	White or Blue	Red or Yellow
Shape of water valve	Has no stand offs within	Has four stand offs visible within
plunger	outlet nozzle	outlet nozzle

Always check the resistances when replacing the Motor Controller. If the resistance is low always replace the water valve. Remember if the valve is hot the resistances can increase by as much as 50%. The fault numbers associated with the water valves are 33, 48, 49 and 50. If inlet water is 5 litres a minute flow or less, flow restricting washers may be removed from water valves. Large bore inlet hoses p.n. 426123 should be used in these circumstances.

The water valves may be manually turned on from Diagnostic Mode. Press ‘Wash Temp Down’ and ‘Power’ buttons together. Phase 3 Only press ADVANCE key once. The ‘Wash Temp Down’ button turns the cold water valve on or off. The ‘Cold Water’ LED will turn on. The ‘Wash Temp Up’ button turns the hot water valve on or off. The ‘Hot Water’ LED will turn on. NB. Phase 2 it is possible to latch water valves on in this mode. Power off at the wall to resolve.
