Problem: Wash motor runs continuously.
1. NORMAL/DELIME switch is in "DELIME" position. Place the switch in the "NORMAL" position.
2. Wash relay welded closed. Turn the machine off. If the wash relay doesn't release, replace contactor.
3. Faulty timer, check voltage between J3-2 and RED wire if always reads voltage replace timer.
Problem: Low wash water pressure.
1. Water level is too low. Increase the fill time, or decrease the drain time, and verify that incoming water pressure is 20A5 PSI.
2. Sump strainer clogged. Clean and re-install.
3. Obstruction in either the wash pump housing or the wash manifold. Disassemble and clear obstruction.
4. Clogged wash arm nozzles. Remove the wash arms, clean the nozzles, then re-install.
Problem: Dishmachine keeps tripping the service breaker.
1. The power supply may be shorting to ground. Check for loose wires or burned connections.
2. Pump impeller jammed. Clear the impeller.
3. Wash motor faulty. Check the motor voltage and amperage draw. If amperage draw is over 12 amps, replace the motor.
4. Heater faulty. Check amp draw on wires to element, if redings are not balanced, replace element.
Problem: Dishmachine will not hold water.
1. Faulty drain ball. Replace as necessary.
2. Drain hole may be obstructed. Remove the obstruction.
3. Drain rod bent or binding. Repair the rod, or replace as necessary.
Problem: Chemical pump(s) not feeding.
1. Push prime switch on dispenser. If pumps run check timer, if they don't run check pump motors for continuity, if open replace
2. Faulty timer. During fill, measure the voltage between the ORANGE/BLACK and RED wires and BLACK/YELLOW and RED
wires. If it reads 120 volts, timer is okay. If there is no voltage check wires and connector for continuity, if okay replace timer.
