is not lit or wiring short (does not apply to S.S. The start switch or scrub switch failed in the closed
Pizio switch on models (UH130, UH130B, UH230, UH230B) position, or there is a wiring short
Machine is powered up and Run LED Check voltage
is not lit after unplugging the low
voltage plug
2. Wash pump runs but nothing else works 4 amp board output fuse is blown
Replace the 4 amp fuse. Check for wiring problem
3. Check continuity of the start switch Use plug pin #8, wire #15 as common to plug pin # 1,
wire #20 (see Fig.1)
Check continuity of the scrub switch Use plug pin #8, wire #15 as common to plug pin # 3,
wire #19 (see Fig.1)
Check continuity of the cycle light Use a meter with diode setting - to cycle light, plug
pin # 6, wire #16 and common pin # 8, wire # 15
Check continuity of the scrub light Use a meter with diode setting - to scrub light, plug

Check continuity of door safety switch Use a meter with diode setting - to door safety switch,
plug pin # 4, wire #18 and common pin # 8, wire # 15
4. Fill LED is lit Indicates output voltage to fill valve
5. Select the appropriate setting on the Note: This solid state timer board is used for Set dipswitch to FWR for models UH230, UH230B
dipswitch for the model of machine several different models Set dipswitch to F&D for models UH130, UH130B, UL130
the solid state timer will be installed in
6. Use the skip switch to force the timer
