CHEMICALS AND PUMP ADJUSTMENT

Dishwashers require the use of a detergent and possibly a rinse additive. The detergent must be of commercial strength to work in the unit’s short cycle. The rinse additive will help the water to sheet on the glasses and plates, acting as a drying agent.

The products are a Sodium Hydroxide for the detergent and a surfactant isopropanol for the rinse. Quantities will vary with water quality but as a guideline there should be 200 ppm for the detergent and 50 ppm for the rinse-agent. Those products are available from any chemical company. Never use chlorinated product such as sanitizer and bleach. These products can damage the equipment.

Should you run out of these products, you can use residential brand product as a temporary measure. Do NOT use soap that produces suds. Use those product that are sold for dishwashers. Good quality chemical product will improve the washing.

Models 727, 737, F-16, F-16DP, F-18, F-18DP & F-20 are supplied with a factory installed liquid detergent pump to automatically dispense detergent into the wash tank chambers. Before accessing the bottom section of the dishwasher, make sure that the power was turned off at the source (breaker panel).

The bottom panel can only be remove with a flat tool like a screw-driver. Insert the screw-driver in the gap between the front panel and the side panel. Pry open towards you. Do this on both side.

The clear hoses connected to the pumps must be pulled out and fed through the bottom of the dishwasher. The containers can be either to the right or left of the dishwasher. Perforating the stainless panel is not recommended.
