PART 8: COMPONENT REPAIR AND REPLACEMENT (Cont.)
8.2 Components
This section provides photos, illustrations and basic instruction for the removal and replacement of the main
components of the dishwasher. It does not cover all components such as the wash arm supports, hoses or
panels. These repairs require simple observation and basic mechanical skill and therefore are not included in
this manual.
Chemical dispensing pump installation is covered in Section 2.10,
Installing Optional Chemical Pumps
, pages
21-23.
WARNING:
Machine surfaces are hot during and after normal operation.
WARNING:
When working on the dishwasher, disconnect the electrical service and place a red tag at the
disconnect switch to indicate work is being done on that circuit.
WARNING:
Use extreme caution when testing circuits while power is applied to the machine.
8.2.1 Pressure Reducing Valve (PRV) Adjustment
UH-200B, UH-200 Only
A 3/4" PRV is required if the incoming water supply exceeds 20-22 PSI/138-151 kPa flowing pressure.
The PRV should be installed in the incoming water supply line before the machine connection.
To adjust the PRV:
1. Loosen the locknut on the adjusting screw
in the top of the PRV.
2. Turn the adjusting screw CW to increase
the flowing pressure to the machine.
3. Turn the adjusting screw CCW to reduce
the flowing pressure to the machine.
4. Observe the pressure reading on the control
panel to confirm the proper setting of
20-22 PSI/138-151 kPa during the final rinse.
5. Tighten the locknut on the adjusting screw.
6. If the proper pressure cannot be achieved
then check the water pressure before the
PRV, it may be too low, or replace the PRV.
