MAINTENANCE

To maintain performance and prevent trouble, it is important to check the outside and inside of the dishwasher, including filters and spray arms, at regular intervals.

WARNING

• When cleaning the outside and inside of the dishwasher, do not use benzene or thinner.

Otherwise, it may cause fire or explosion.

• To prevent injury during care and maintenance or cleaning, wear gloves and/or protective clothing.

NOTE

• If you have not used the dishwasher for a long time, refresh the inside by running the Machine Clean cycle without detergent. When the cycle is finished, clean the inside and outside of the dishwasher according to the Maintenance instructions.

Cleaning the Exterior

• In most cases, the exterior of the dishwasher can be cleaned with a soft damp cloth or sponge, then dried with a soft cloth. If the dishwasher has a stainless steel exterior, use a stainless steel cleaner.

CAUTION

• If cooking oil is spilled on the exterior of the product, wipe it off immediately. Do not clean the exterior of the product with cleaners which contain alcohol, thinners, bleach, benzene, flammable liquids, or abrasives. These substances may discolor or damage the appliance.

Cleaning the Interior

• Clean the interior of the dishwasher periodically with a soft, damp cloth or sponge to remove food and dirt particles.

• To remove white spots and odor from inside the dishwasher, run an empty cycle, without detergent, with one cup of white vinegar in a dishwasher safe glass or bowl placed on the upper rack. (Vinegar is an acid and with constant use it could damage the appliance.)

Seasonal Maintenance and

Storage

• If you will be absent for an extended period of time during warmer months, close the water valve and disconnect the power supply line, or turn off the circuit breaker. Clean the filter, tub and dispenser to prevent odor.

• If you will be absent for an extended period of time during colder months and there is a possibility of freezing temperatures, winterize the water supply lines and the dishwasher itself. Winterization must be performed by qualified service personnel.

Clogged Drain Air Gap or

In-Sink Disposal

Check the drain air gap or in-sink disposal if the dishwasher is not draining well.

Cleaning the Air Gap

1 Turn off the dishwasher.

2 Remove the air gap cover and the plastic cap underneath it.

3 Clean out any debris with a toothpick or brush.

4 Replace the plastic cap and air gap cover.

NOTE

• The drain air gap and disposal are external plumbing devices that are not part of the dishwasher.

• The warranty provided with the dishwasher does not cover service costs directly associated with the cleaning or repair of the external drain air gap and disposal.

Cleaning the Filters

1 Remove the lower rack and position the bottom spray arm so a wider vee is open to the front.

2 Turn the inner filter counter-clockwise and take out the assembled inner filter and stainless steel filter.

With the filters removed, check the sump opening and remove any foreign materials, if needed.

WARNING

• Be cautious of sharp edges when handling the stainless steel filter.

3 Clean the filters with a soft brush under running water. Reassemble the filters before reinstalling them.

CAUTION

• Remove food residue caught in filters to prevent the build up of odor-causing bacteria and possible drainage problems.

NOTE

• For best wash performance, clean the filter after each load. If food debris remains in the filter, it may cause an odor.

• In areas with hard water, clean the filter at least once a month with a soft brush.

• Clean the filters using non-abrasive materials and warm running water.

• Make sure the filter is assembled correctly before starting a cycle. When assembling, rotate it firmly until it clicks.

4 To replace the assembled filters, position the spray arm so the wider vee is toward the front. Fit the filters back into the filter holder and secure them by turning the inner filter clockwise until it clicks into place.
