Frequently Asked Questions - UH130 Champion

How do I clean the filters of my Champion UH130 dishwasher?

Turn off the dishwasher, remove the bottom rack, twist and lift out the filter assembly. Rinse under running water with a soft brush. Reassemble securely.

Why is my dishwasher not draining water?

Check if the drain hose is kinked or blocked. Clean the filter and ensure the garbage disposal (if connected) is clear. Run a rinse cycle.

What detergent should I use?

Use a dishwasher detergent in powder, gel, or tablet form. Avoid hand soap or liquid dish soap as they cause oversudsing.

How do I add rinse aid?

Open the rinse aid dispenser on the door, pour until full (usually a line indicator). Close the cap. Adjust the setting from 1-6 depending on water hardness.

My dishes are not drying completely. What should I do?

Ensure rinse aid is filled and setting is adequate. Use a higher temperature rinse cycle. Leave door slightly ajar after cycle for steam to escape.

How do I start a delayed wash?

Select the desired program, then press the delay start button repeatedly to set the delay time (1-24 hours). Close the door, the cycle will begin after the delay.

The dishwasher is making a loud noise during operation. What could be wrong?

Check for large food particles in the filters, or items blocking the spray arms. Ensure dishes are properly loaded and not hitting each other. Run a cleaning cycle.

How often should I descale the dishwasher?

Descale every 3 months or when you notice limescale buildup. Use a commercial dishwasher descaler or a mixture of citric acid and water.

Can I open the door during a cycle?

Yes, the dishwasher will pause once the door is opened. Close it and press start to resume. Be careful of hot steam and water.

What does the 'Salt' indicator mean?

It indicates the salt container needs refilling. Open the cap on the bottom of the tub, add dishwasher salt (not table salt) until full, then replace cap.

Booster Heater/Wash Tank Heater Interlock Circuit Operation

For Models UH130B, UH230B The booster heater/wash tank heater interlock circuit removes power from the wash tank heater whenever the booster heater contactor energizes. The illustration below shows how the booster heater contactor is wired.

The booster heater contactor is located behind the lower front access panel.

Interlock Circuit Operation

1. The dishwasher fills with water when the main power switch on the dishwasher is turned on. The booster heater thermistor calls for heat which energizes the booster heater contactor.
2. The auxiliary contact on the top of the contactor opens and removes power from the wash tank heater.
3. When the booster heater thermister is satisfied, the booster heater contactor de-energizes and the auxiliary contacts close applying power to the wash tank heater.
4. This operation is repeated whenever the booster thermistor calls for heat.

Undercounter Temperature Display Board Updates — P/N 0512106

1. The new version for the undercounter display board is larger than the display board used on previous models.
2. The new version board mounting holes are in the same location as the old board and will mount in the machine as before.

Diagnostics

A - When testing the circuit board operation, disconnect the harness from this plug. The wash and rinse displays will display E.B - Push and hold the rinse test pushbutton. A numerical value of 179-180 should appear in the rinse temperature display window indicating the circuit board is operating normally.C - Push and hold the wash test pushbutton for 10 seconds A numerical value of 140 should appear in the wash temperature display window indicating the circuit board is operating normally.

Temperature Adjustments

When performing diagnostics the values are displayed in °F even if the display is set for °C.A F/C Slide switch is provided on the board to change the display from the factory default setting of °F to the optional °C.D - Turn clockwise to increase the booster temperature. Full range is 3/4 turns 180-200°F. DO NOT FORCE PAST THE STOPS.E - Turn clockwise to increase the wash temperature. Full range is 3/4 turns 120-160°F. DO NOT FORCE PAST THE STOPS.

Test/Condition Indication/Cause Recommendation/Solution

1. Run LED is lit	Board has power
Machine is powered up and Run LED is not lit	Possible bad start switch, scrub switch or wiring short (does not apply to S.S.Pizio switch on models (UH130, UH130B, UH230, UH230B) position, or there is a wiring short		Unplug low voltage plug. If Run LED lights up:The start switch or scrub switch failed in the closed
Machine is powered up and Run LED is not lit after unplugging the low voltage plug			Check voltage
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 pi			in # 3, wire #19 (see Fig.1)
Check continuity of the cycle light Use a meter			ug pin # 6, wire #16 and common pin # 8, wire # 15
Check continuity of the scrub light Use a meter			ug pin # 7, wire #17 and common pin # 8, wire # 15
Check continuity of door safety switch Use a m			y 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 dipswitch for the model of machine the solid state timer will be installed in	Note: This solid state timer board is used for several different models		Set dipswitch to FWR for models UH230, UH230B Set dipswitch to F&D for models UH130, UH130B, UL130
6. Use the skip switch to force the timer to the next segment of the cycle			Eg: Pressing the skip switch immediately after starting the cycle will make the machine skip the wash cycle, and go straight into the drain cycle
7. Use the reset button to reset the solid state timer board	The reset button will reboot the solid state timer board (much like rebooting your computer)
8. 0.063 amp internal board supply fuse is blown			Replace the solid state timer board
9. Wash motor LED is lit	Indicates output voltage to the wash motor during wash/rinse cycle only. LED is not lit during soft start
Wash motor LED is not lit, but wash motor runs continuously			Replace the board

Diagnostic Testing for p/n 0712105 Solid State Timer Board - effective serial # W081217467 and up

1. Before testing, turn the power switch OFF and allow the machine to complete the drain cycle.

Check incoming voltages

2 Open the door

If the green cycle indicator light blinks, the DOOR SWITCH and CYCLE LIGHT work Note: This function times out after 10 seconds

Close the door

3 Press and release the START SWITCH

If the green cycle indicator light flashes the start switch works

4 Press and release the SCRUB/EXT WASH switch if equipped

If the green indicator light for the scrub switch flashes, the scrub/ext wash switch works

5 To test the timer board and the following components, press and release the start switch 3 times with the door closed

If the components listed below are operating properly, they should run consecutively for a few seconds each

fill valve •

detergent pump•

rinse-aid pump•

drain valve opens•

drain valve closes•

wash pump•

drain pump or sanitizer pump (if applicable)

If one or more components do not run, see below

CONDITION

One of the components in step 5 does not run

The wash pump is the only component that runs

The wash pump is the only component that will not run and the 4 amp fuse is good

None of the components run in step 5 Check neutro

POSSIBLE CAUSE/SOLUTION

Check the component that did not run

Check the 4 amp fuse on the timer board

Check pump motor/See troubleshooting guide
