SYMPTOM

 

POSSIBLE CAUSES

 

Unexpected results on

1.

Etching — usually caused by any combination of high

 

dishes.

 

temperatures, soft water, soft glass, or high alkaline washing

 

 

 

solutions.

 

 

2.

Tarnishing — avoid washing silver, silver plate and pewter in

 

 

 

chemical sanitizing machines.

 

 

3.

Pitting — stainless steel may pit with lengthy contact of foods

 

 

 

containing 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

 

 

 

dishwasher cleaning.

 

 

10.

Plastic ware distortion — high temperatures. Check plastic

 

 

 

ware's instructions.

 

 

 

 

 

Low temperature readings.

1.

Low water supply temperature — make sure it meets the

 

 

 

recommended limits.

 

 

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 — set for higher value on

 

 

 

LX40H; call Hobart Service Technician for LX18H and LX30H.

 

 

 

 

 

Machine won't fill or won't

1.

Low water pressure — check for clogged hose strainer; check that

 

fill high enough.

 

site water pressure meets minimum flow pressures.

 

 

2.

Make sure probes are clean (see Cleaning, page 22).

 

 

3.

No water pressure — main water supply valves may not be
