6.4 Troubleshooting Guide

The following checklist provides general guidelines for evaluating trouble conditions with the
dishwasher. Detailed troubleshooting flow charts are provided in Part 11 at the end of this
manual.

STEP 1:

The first step in troubleshooting the dishwasher is knowing how it works under normal
conditions. Review Part 3, Operation, pages 27-34, for a description of proper loading,
operator controls and basic operating procedures.

STEP 2:

Check the general condition of the dishwasher.

•

Does the dishwasher appear level?

•

Are the spray arms and screens clean and in place? Is the door fully closed?

STEP 3:

Some problems may be resolved by double-checking the supply connections to your dishwasher.

Perform the following steps to double-check the dishwasher service connections.

•

Push the POWER button on the dishwasher OFF, then
Turn the main power OFF at the main service disconnect switch or fused circuit breaker.
If your dishwasher has a cord and plug, disconnect the plug and reconnect.
Turn the main power ON and recheck the dishwasher operation.

•

Turn the dishwasher water supply valve OFF and back on again.
Check the flexible water supply hose at the rear of the machine. Is it kinked?

•

Check the water temperature supplied to the dishwasher.
Are building water heaters operating correctly?

•

Check the flow of the building drain system.
Are any drains clogged or running slow?
Check the flexible drain hose at the rear of the machine. Is it kinked?

•

Check the chemical dispensing supplies? Are the strainers clean?
Are the pick-up tubes in the correct containers?

STEP 4:

Refer to Section 6.3, Error Codes, page 49-50. Observe the self-diagnostics display when the
dishwasher is first powered up. Many problems can be identified by evaluating the diagnostics.

STEP 5:

Refer to Part 7, Solid State Circuit Board Set-up and Repair, next page. Double-check the
jumper settings on the circuit boards and observe if LED’s on the boards indicate an
error condition.
