Remove the bulkhead plug in the side of the tub to install the detergent concentration probe. PREPARATION: Before proceeding with the start-up of the unit, verify the following: 1. Close door(s) on dishmachine.
TROUBLESHOOTING SECTION Problem: Nothing on dishmachine operates. The power switch is ON and the power indicator light is OFF. 1. Machine is not wired correctly to incoming power source. Have an electrician verify wiring. 2. Machine circuit breaker is tripped. Reset the circuit breaker. If it trips again, contact an electrician to verify the machine amp draw. 3. Service breaker is tripped. Reset the service breaker. If it trips again, contact an electrician to verify the machine amp draw.
TROUBLESHOOTING SECTION (CONTINUED) Problem: Spotting of silverware, glasses and dishes. 1. Incorrect final rinse temperature. Verify that the rinse water temperature matches that which is listed on the machine data plate. 2. Clogged wash and/or rinse nozzles and arms. Remove the arms and verify that they and their nozzles are from debris. 3. Excessively hard water. Install a water softener to reduce hardness. 4. Loss of water pressure due to clogged/obstructed wash pump.
