Model Serial Number Number Purchase Do,e Service Company and Telephone Number 3 POWER CLEAN* Washing System Your dishwasher cleans by spraying a mixture of hot, clean water and detergent against soiled surfaces of dishes. When a cycle is started, the dishwasher fills with water to about the level of the heating element. This water is pumped through the rotating spray arms, through the POWER CLEAN Module which removes food particles, and back through the rotating spray arms. Soiled water is pumped out and replaced with clean water during a cycle - the number of times depends on the cycle being used. The POWER CLEAN* Module removes food particles from the water, stores them, then washes them down the drain. Load dishes so soiled surfaces face erful spray from rotating arms. Step-saving preparation pow- for washing It is not necessary to rinse dishes before putting them into the dishwasher. Just remove large pieces, bones, and other hard items. The POWER CLEAN Module will remove food parti- cles from the water. It contains a chopping device which will reduce the size of food items. If hard items such as fruit seeds, nuts and egg shells enter the POWER CLEAN Module, you might hear chopping, grinding, crunching or buzzing sounds. Those sounds are normal when hard items enter the module. DO NOT LET METALLIC ITEMS GET INTO THE POWER CLEAN MODULE. Hot water is a must Hot water dissolves and activates the dishwashing detergent. Hot water dissolves grease on dishes and helps dry y glasses spot-free. Make certain loads are washed in hot water (at leastl40”F 60°C). Two ways to Check Water have a reliable hot Temperature water supply... 1. Maintain 140°F water supply at central water heater. To check water temperature, 4 turn on hot water faucet nearest the dishwasher. Let water run until it is as hot as possible, then check with a candy or meat thermometer. If the temperature is too low, have a qualified person raise the water heater thermostat setting. 2. Use HI-TEMP WASHING Option. If water heating is needed, a thermostat will delay the cycle until temperature reaches 145°F (63°C). If water is hot enough, the cycle will proceed with no delay. This lets you tUrfi down your water heater, if you choose, without cutting back on hot water needed for good dishwashing. *Tmk.

Test one piece by washing it doily in the dishwasher for several weeks. Then compare it with the rest of the set to see if colors have changed. Delicate, antique items should be hand washed. Crystal and glasses: Load carefully in top rack only. Load between prongs-not over them -to help prevent bumping and chipping. Load a few larger items in the bottom rack to reduce amount and force of water spray reaching glassware from the bottom spray arm. Use the shortest washing cycle [see page 9). Delicate, antique items should be hand washed. Flat ware: Salty and acidic foods may tarnish silver and stainless flatware if allowed to remain on the utensils. Rinse flatware as soon as possible especially if it IS not to be washed right away. Clean tarnished items with silver polish. Antique finishes may be removed by the dishwasher detergent.

The air gap is usually located above the sink or on the lop of the counter near the dishwasher to prevent the possibility of water bucking up from the drain into the dishwasher due to a plugged drain. The drain air gap is NOT a part of the dishwasher and is NOT covered by the dishwasher warranty. The drain air gap should be kept clean to insure proper draining of the dishwasher 13 If you need service or assistance, we suggest you follow these four steps: 1. Before calling for assistance.. . 3. If you need service * . . . Performance problems often result from little things you can find and fix yourself without tools of any kind. 1. If dlshwarher won’t run, or stops during cycle: Is door tightly closed and securely latched? Has cycle been correctly set (and Control Knob pulled out)? Is water turned on? Has house fuse blown or circuit breaker tripped? Is the power cord plugged in (if so equipped)? Has electrical power been interrupted? If motor has stopped because of overload, it will automatically reset itself within a few minutes. If motor does not start, call for service. Are you using the POTS & PANS Cycle or HI-TEMP WASHING Option? Is the dishwasher waiting for water to heat? 2. If water remains in the dishwasher: l Has the cycle completed? l Is drain air gap clogged? 3. If detergent remains In the covered detergent cup: l Is the bottom rack in backwards? (The rack bumpers should be at the front.) l Is the dishwasher detergent fresh and dry without lumps? l Is the cycle completed? 4. If you hear grlndlng, grating, crunching, burzlng sounds: l A hard object has probably entered the POWER CLEAN Module. The sound should stop when the object is ground up. 2.
