Possible Causes
Unexpected results on
dishes.
1. Etching – usually caused by any combination of high temperatures,
soft water, soft glass, or high alkaline washing solutions.
2. Tarnishing – avoid washing silver, silver plates, and pewter in chemical
sanitizing machines.
3. Pitting – stainless steel may pit with lengthy contact of foods con-
taining salt, fruit juices, vinegar, etc. Wash immediately.
4. Black or gray marks – may have been rubbed with aluminum.
5. Brown stains – may be due to high iron content in water supply.
6. Chipping – improper loading or ware is too delicate.
7. Fading of china patterns – usually due to high water temperature
and strong detergent. Check that china is dishwasher compatible.
8. Wooden ware damage – avoid washing in dishwasher.
9. Rust on cast iron – seasoning is lost in dishwasher. Avoid washing in
dishwasher.
10. Plastic ware distortion – high temperatures. Check plastic ware's
instructions.
Low temperature readings.
1. Low water supply temperature – make sure it meets the recom-
mended minimum temperature.
2. Rapid cycle use – if incoming water temperature is low and cycle use
rate is high, the hot water supply may be insufficient to meet the
demand.
3. Heavy ware load cools wash water – do not overload racks.
4. Booster heater or sump heater set low – contact your local service
provider.
Machine will not fill or will not
fill high enough.
1. Low water pressure – check for clogged hose strainer; ensure the site
water pressure meets minimum flow pressures.
2. No water flow – main water supply valves may not be working.
Machine fills too high or
leaks from door.
1. Machine not level. (see LEVELING.)
2. Fill solenoid valve leaking – power the dishwasher OFF; if water con-
tinues to flow into the machine, contact your local service provider.
Machine will not drain.
1. Drain pipes restricted – check dishwasher drain line for kinks; ensure
proper drain rate is allowed from plumbing.
2. Power machine OFF. Wait several seconds and then power back ON.
Repeat this procedure twice if necessary. If problem persists, contact
your local service provider.
Some water occasionally drips out
of rinse arms (high temperature
dishwashers only).
This is normal due to expansion of water being heated in the booster
tank.
