MAINTENANCE OF THE SHIPBOARD WASHER EXTRACTORS
The washer extractor is a very important and expensive piece of equipment. If it breaks down, time and money are consumed, perhaps un-necessarily, and the ship's company may be subjected to inconveniences and unsanitary living conditions. Therefore, too much emphasis cannot be placed on the proper care and maintenance of the washing machine. The senior laundry petty officer and all operators are responsible for the care of washer extractors. The washer should be kept as clean inside and outside as possible. Soap solutions and hot water help to keep the inside clean and sanitary, but scum and other accumulations should be removed daily from the exterior. An oxalic acid solution made by dissolving 1/ 2 pound of oxalic acid crystals in a gallon of water can be used to keep the outside of the tub clean and bright. Use a rag or brush to apply the solu-tion. Rub vigorously and then rinse with clean water. A fine abrasive powder, such as pumice stone, sprinkled on the damp cloth helps to remove grease and film from the tub. Scouring powder and a brush vigorously applied also work quite well.

As an operator, be alert for mechanical problems that may occur between maintenance checks such as the following:
Loose latches on cylinder doors
Leaky valves
Extractor brake working improperly
Thermostat working improperly
Switches inoperative
Timer operating improperly
Extract engages roughly
Water levels incorrect
Safety features inoperative

Laundry personnel should not attempt mechanical or electrical maintenance. Remember, hands off electrical wiring in the electrical box. All mechanical or electrical maintenance must be done by qualified shipboard maintenance personnel.
