9.6 The water gets too hot and stops the machine.
Possible Cause
1. Incorrect soap is creating too much foam. (Foam causes excess heat by
reducing the efficiency of the pump and it insulates the top of the tank which
holds in heat).
2. The Triac has failed and is passing current to the heater when it is turned off.
Solution
1. Change the wash solution and use a low foaming soap designed for continuous
ware washing or reduce the quantity of low foaming soap that is added to the
water.
2. With the machine operating, check the amperage on the heating element wires
when the indicator light goes off. If the current does not go off when the indicator
light is off, the Triac is defective.
9.7 The chemical dispenser pump runs, but does not pump the
chemical.
Possible Cause
1. The hose has been punctured or ruptured.
2. The fitting has not been screwed onto the chemical container properly.
Solution
1. Replace the defective hose with a new hose.
2. Unscrew the fitting from the container; check the threads and face of the fittings
for damage. Carefully screw the fitting back onto the container so that the fitting
seats properly against the container opening.
