Reference the appliance manufacturer's operations manual to confirm the electrical and water requirements necessary to operate your individual RV dishwasher. Electrical power is generally supplied through shore power or the RV generator. Maximum water usage per cycle averages from six to three gallons, depending on the type of dishwasher. Dishwasher operations during dry camping will require that you confirm there is adequate supply within the fresh water holding tank to perform the full cycle, as well as ample space within the gray water holding tank for RV dishwasher drainage.

Prior to operating the dishwasher, confirm that the RV is level. Remove excess soil from dishes before loading items into the dishwasher racks. Protect delicate glassware by placing these items in the upper rack only. Turn sharp items downwards, and away from the door, to prevent damage to the door seal. Avoid overfilling the dishwasher and forcing the door to close. Assure that you have left adequate room for the sprayer arm inside of the dishwasher to reach all surfaces.

Fill the labeled soap dispensers with manufacturer recommended detergent. Never add liquid dish detergent designed for sink washing, or laundry soaps for use in washing machines. Detergents other than those recommended by the manufacturer for the specific type of dishwasher can create excess suds that will harm the appliance components. When directed to use powdered detergent, avoid tablets or aged soap that has hardened and may not dissolve. If applicable, add a rinse agent to the appropriate dispenser to further aid in cleansing dishes.

Engage the ceiling exhaust fan to remove hot, humid air generated by the dishwasher when in operation. Select the preferred wash program, close the door and press the Start button. Appliances that include a Start/Pause button can be interrupted during operations by pressing the Pause button. Once the dishwasher has run a normal course, allow the drying fan to complete the dry cycle before opening the door.

Read the operations manual of your specific dishwasher to determine what components will require regular inspection and maintenance. The information will also assist you in pinpointing troubleshooting concerns. Leave sufficient space around the dishwasher hoses and plugs located under the counter to lessen the chance of damage from items colliding during road travel, and to easier access the hoses for troubleshooting purposes.

In the event that the dishwasher does not fill with water, check that the water is turned on, and that there is sufficient amounts of water to supply the on board dishwasher. Other possible causes could be a loose hose, or clogging at the inlet.

Failure to properly drain can include a clogged strainer, pump or drain valve. Inspect the drain hose located under the counter to assure storage items have not shifted and caused the drain hose to kink.

Insufficient water temperature may result in the dishes appearing unclean following a usual wash cycle. To check the water temperature, place a cooking thermometer under the flow of hot water at the faucet nearest to the dishwasher. If that temperature is lower than recommended by the dishwater manufacturer, consider turning up the hot water heater thermostat. Additional causes for improper cleaning may be due to a clogged strainer or sprayer, broken detergent dispenser, or old detergent that did not dissolve.

If the dishwasher leaks, or overflows, confirm the door gasket is snug and secure. Inspect for a clogged valve, loose hose clamp, or defective pump seal. Road vibration may have caused the dishwasher to move out of appropriate position. Confirm that the component is level, and if necessary, readjust. The use of excess detergent can produce oversudsing that results in leaking. Inspect the cut off switch, which may be stuck or requires replacement.

Do not spray ammoniated cleansers directly onto the dishwasher components. Clean the control panel using a slightly damp cloth with warm water or a specially designed appliance wax. Avoid the use of abrasive cleansers, scrapers or scouring pads that can scratch the finish. With a clean damp cloth, regularly wipe around the door seal to remove stray food particles.

Occasionally, you may want to clean the interior of the dishwasher using a mild non-abrasive cleanser. If you detect a white powdery coating on the dishwasher interior, a rotten egg odor, or a rusty discoloration, this could indicate a hard water source. When traveling in areas that include hard water conditions, consider running the dishwasher through an empty cycle using one cup of white vinegar at least one time per week.

Washing dishes by hand can often use twice the amount of water required by the on board dishwasher. Take further advantage of this savings in water use by only running the appliance once it has been filled to manufacturer recommended levels. During storage of the RV, disconnect the power and water supplies to the appliance, thoroughly clean the interior box, and leave the front door ajar for adequate airflow. For winterization recommendations, consult the manufacturer's operations manual.

RV dishwasher units can be purchased as an after-market addition, but will necessitate the sacrifice of galley storage. Prior to purchasing a dishwasher to install in your RV, test the unit to insure that the electrical and water demands are within your camping supplies, and that during operations the appliance generates minimal noise to compete with the living area.
