    Why does my Champion UH330 ADA Test Equipment have poor wash results?
    • C
      Caleb HamiltonAug 4, 2025
      Poor wash results from your Champion Test Equipment can stem from several factors. Excessively hard water may be the cause, so contact your chemical supplier. Other potential issues include a defective thermistor (replace it), a defective detergent injector (replace the squeeze tube or injector motor, and clean the tubing and pick-up), a blown chemical circuit board fuse (contact service agent), incorrectly loaded wares in the dishrack (reposition wares or reduce the amount), a tripped booster or wash tank high limit (reset or replace the high limit), or clogged rinse arm nozzles (clean nozzles with a small paper clip).

    What to do if my Champion Test Equipment has low or no water?
    • T
      Timothy BoyleAug 8, 2025
      If your Champion Test Equipment is experiencing low or no water, it could be due to several reasons. First, check if the main water supply is off and open the supply valve. Also, inspect the fill hose for any kinks and straighten it. Ensure the flowing water pressure is set to 25-95 PSI. If the solenoid valve is defective, install a repair kit or replace it. Lastly, check for a clogged solenoid strainer and clean it.

    How to fix a Champion UH330 ADA dishwasher that will not run?
    • E
      Eric ScottAug 13, 2025
      If your Champion Test Equipment dishwasher won't run, make sure the door is completely closed. Check the breaker on the panel to ensure the main power is on. Verify that the dishwasher power switch is turned ON. If these steps don't resolve the issue, the circuit board fuse may be blown, and you should contact a service agent.

    Why are chemicals not feeding into my Champion Test Equipment dishwasher?
    • J
      Jessica WoodAug 17, 2025
      If chemicals aren't feeding into your Champion Test Equipment dishwasher, start by checking if the chemical supply is low and refill the chemical container. Inspect the supply tubing for damage or kinks; replace or straighten the tubing as needed. Also, check for a clogged pick-up tube and clean or replace it. If the chemical circuit board fuse is blown, contact a service agent. Finally, a defective pump squeeze tube may be the culprit, so replace the squeeze tube.

    How to increase water pressure in Champion Test Equipment wash spray arms?
    • P
      Paul CannonAug 21, 2025
      If you're experiencing low water pressure from the wash spray arms in your Champion Test Equipment, it could be due to a clogged scrap screen, clogged spray arms, or a clogged pump intake. Clean the scrap screen and spray arms. Inspect the sump and clean the pump intake.

    Why is water draining from my Champion UH330 ADA's wash tank when idle?
    • J
      Johnny ChristianAug 26, 2025
      If water has drained out of the wash tank of your Champion Test Equipment while it was idle, it might be because the anti-siphoning loop in the drain hose has been removed. Re-route the drain hose, but do not stretch it. Also, the drain hose clamp might not be holding the drain hose in the proper position; replace or adjust the hose clamp, making sure the goose-neck is maintained. If the issue persists, the building plumbing may not provide the correct air vent to prevent siphoning; contact a service agent and/or plumber.

      The Rinse Sentry extends the wash mode for a maximum time of 5 minutes to allow the final rinse water booster temperature to reach 180°F/82°C. Contact service agent.
