1-2 n 18” & 24” ADA Built-In Dishwashers

GENERAL INFORMATION

General Information

Filtration System and Maintenance

Your dishwasher has a ltration system that

 

ef ciently removes food particles from the

 

wash water.

Coarse lter

The lter system consists of three parts:

 

a ne lter plate, a coarse lter, and a

 

lower lter.

Fine lter

IMPORTANT: To avoid damage to

 

dishwasher, do not operate your

Lower lter

dishwasher without lters properly

installed. Be sure lower lter is securely

 

in place and upper lter assembly is locked

 

into place. If the coarse lter turns freely,

 

it is not locked into place.

 

The lters may need to be cleaned when:

Visible objects or soils are on ne lter plate. Dishes feel gritty to the touch.

See the “Filtration System” section in the full User Instructions for complete removal and maintenance schedule.

IMPORTANT: Do not use a wire brush or a scouring pad, etc., as they may damage the lters.

Rinse lter under running water until soils are removed. If you have hard-to-remove soils or calcium deposits because of hard water, a soft brush may be required.

Drying – Rinse aid is essential

You must use a drying agent such as a rinse aid for good drying performance. Rinse aid along with the Heated Dry option will provide improved drying and avoid excessive moisture on the dishwasher interior.

Press START every time you add a dish

If anyone opens the door after the dishwasher has started (such as for adding a dish, even during the delay time), the Start button must be pressed again to resume the cycle.

Press START and push the door •rmly closed.

Adjust Upper Rack

You can raise or lower the upper rack to •t all items in either the upper or lower rack.

To raise or lower the rack:

Empty the rack. Pull the rack out halfway and take notice of the position of the carriage wheel assembly and side rail on each side of the rack. Lift up on the front of the rack while pulling the rack out all the way. The rack will then be completely free of the side rails. Reverse this action to re-engage the rack's carriage wheels onto the rails in the higher or lower position desired.

NOTE: The upper rack must be level.

Dishwasher Care

Cleaning the Exterior

Clean the exterior of the dishwasher with only a soft, damp cloth and mild detergent. Avoid using abrasive cleaning products on the exterior of the dishwasher.

Cleaning and Maintaining the Interior

Many detergents may leave white spots or a white residue on dishware and on the interior of the dishwasher. Over time this residue can become unsightly and could affect dishwasher performance. Use of a dishwasher cleaning product such as affresh® Dishwasher Cleaner can help to remove the residue. Monthly use of affresh®

Dishwasher Cleaner is recommended to help maintain the dishwasher. Follow package directions.

NOTE: The manufacturer recommends the use of high-quality premeasured detergent tablets or packs and the use of rinse aid for dishwasher cleaning and daily care.

If you have a drain air gap, check and clean it if the dishwasher isn’t draining well.

To Reduce Risk of Property Damage During Vacation or Extended Time Without Use:

When you will not be using the dishwasher during the summer months, turn off the

water and power supply to the dishwasher.

Make sure the water supply lines are protected against freezing conditions. Ice formations in the supply lines can increase water pressure and cause damage to your dishwasher or home. Damage from freezing is not covered by the warranty.

When storing your dishwasher in the winter, avoid water damage by having your dishwasher winterized by authorized service personnel.

DIAGNOSTICS & TROUBLESHOOTING

For Service Technician Use Only

DANGER

Electrical Shock Hazard

Only authorized technicians should perform diagnostic voltage measurements.

After performing voltage measurements, disconnect power before servicing.

Failure to follow these instructions can result in death or electrical shock.

WARNING

Electrical Shock Hazard Disconnect power before servicing.

Replace all parts and panels before operating.

Failure to do so can result in death or electrical shock.

Voltage Measurement Safety Information

When performing live voltage measurements, you must do the following:

Verify the controls are in the off position so that the appliance does not start when energized.Allow enough space to perform the voltage measurements without obstructions.

Keep other people a safe distance away from the appliance to prevent potential injury.Always use the proper testing equipment.

After voltage measurements, always disconnect power before servicing.

IMPORTANT: Electrostatic Discharge (ESD) Sensitive Electronics

ESD problems are present everywhere. Most people begin to feel an ESD discharge at approximately 3000V. It takes as little as 10V to destroy, damage, or weaken the main control assembly. The new main control assembly may appear to work well after repair is finished, but a malfunction may occur at a later date due to ESD stress.

Use an anti-static wrist strap. Connect wrist strap to green ground connection point or unpainted metal in the appliance

-OR-

Touch your finger repeatedly to a green ground connection point or unpainted metal in the appliance.

Before removing the part from its package, touch the anti-static bag to a green ground connection point or unpainted metal in the appliance.

Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.

When repackaging main control assembly in anti-static bag, observe above instructions.

IMPORTANT SAFETY NOTICE — “For Technicians only”

This service data sheet is intended for use by persons having electrical, electronic, and mechanical experience and knowledge at a level generally considered acceptable in the appliance repair trade. Any attempt to repair a major appliance may result in personal injury and property damage. The manufacturer or seller cannot be responsible, nor assume any liability for injury or damage of any kind arising from the use of this data sheet.

Service Error Codes

DANGER

Electrical Shock Hazard

Only authorized technicians should perform diagnostic voltage measurements.

After performing voltage measurements, disconnect power before servicing.

Failure to follow these instructions can result in death or electrical shock.

Failure Solutions:

1.If an alarm occurs, the machine will enter a failure solving process: The buzzer sounds once per second for 30 seconds. The error code will be displayed. During that time, the drain pump will turn on for 2 minutes.

2.During the drain, if the door is opened, the drain timing will pause.
