Roper Dishwasher Cycle Resetting Repeatedly:... | appliancefaults.com

Technical Background:

The dishwasher's Main Control Unit (MCU) manages the entire wash cycle. It relies on consistent voltage and feedback from various sensors and switches. A voltage dip, an interrupted signal, or a critical component failure can trigger a reset as a failsafe.

Symptoms:

The Roper dishwasher starts a cycle, runs for a short period, and then resets to the beginning or shuts off entirely for no apparent reason. This happens repeatedly. The user has not observed any error codes or other unusual behavior, just the cycle resetting.

Possible Causes:

Power supply issues
Door switch malfunction
Control board failure
Wiring harness problems
Overheating due to pump issues
User interface issues

Solution:

1

Turn off the breaker to the dishwasher.
2

Inspect the door switch with a multimeter for continuity when the door is closed. Replace if faulty.
3

Check the wiring harness connections to the control board for any loose or damaged wires. Use a 1/4-inch nut driver to access the control board.
4

Test the incoming voltage at the junction box with a multimeter; it should read 120V AC. Use a non-contact voltage tester first as a safety precaution.
5

Inspect the control board for any signs of burning or damage. Replace if necessary.
6

Check the drain pump and wash pump for obstructions or overheating. A seized pump can cause a reset.
7

Once repairs are complete, restore power and test the dishwasher through a full cycle.

Safety Warning:

Always disconnect power at the breaker panel before working on any electrical appliance (Lock Out/Tag Out - LOTO procedure). Dishwashers operate on 120V AC, which can cause serious injury or death. Wear appropriate safety glasses and gloves.

Prevention:

Periodically clean the dishwasher's filters and spray arms to prevent clogs and ensure proper water flow. Check the door latch mechanism for proper alignment and function. Run a dishwasher cleaner cycle monthly.

Expert Tip:

Many Roper dishwashers have a service mode. To access it, typically you need to press a specific button sequence (check the tech sheet behind the kick panel). This allows you to run diagnostic tests and view error history, which can provide more specific clues about the cause of the resetting issue.

Frequently Asked Questions

•How can I test the door switch with a multimeter?

Disconnect power. Remove the door switch. Set your multimeter to the continuity setting (or Ohms). Place the probes on the switch terminals. With the switch actuator released (door open), the multimeter should show open circuit (OL or infinite resistance). With the switch actuator depressed (door closed), the multimeter should show continuity (close to 0 Ohms).

•Where is the control board located in my Roper dishwasher?

The control board is usually located behind the front control panel, accessible by removing the screws holding the panel in place. Be careful when handling the control board to avoid static discharge.

•What voltage should I expect at the dishwasher's junction box?

You should measure 120V AC at the junction box. If the voltage is significantly lower, there may be a problem with the circuit breaker or the wiring to the dishwasher.
