Dishwashing Procedures for best results Note: these are general instructions to assist in getting the best performance from Washtech dishwashers – some comments and / or illustrations may not apply to every unit. Installation Read the Operator Manual. Correct installation, including an adequate supply of water at the correct temperature and pressure is essential for effective operation of your machine. Refer installation instructions for details. Drain hose outlet height is important on some models.
Dishwashing Procedures for best results Drying Single tank commercial dishwashers do not have a drying cycle. However, the machines do rinse at high temperatures which promote fast drying particularly when drying agents are used. We recommend prompt removal of the rack from the machine - leave the rack on the bench for 2 to 3 minutes before emptying. This time will be reduced with correct use of drying agent (rinse fluid) which reduces water surface tension and allows water to drain quickly from washware.

Timer Part Number 32822 Function Provides an automatic timing sequence of the wash, rinse, detergent and rinse aid injection stages in a dishwashing cycle. Description The electromechanical timer has a main drive motor and gearbox which produce a full rotation of the seven cams in 180 seconds. The advance motor and gearbox speed the rotation of the timer to produce shorter cycles of 60 and 120 seconds. The timer cams operate individual changeover switches in sequence during the rotation.
Rinse Thermostat Part Number 3020 Function Controls the rinse heating elements and prevents operation of machine if the rinse temperature is below that required. Description The rinse thermostat is a specially calibrated 3 pole capillary type temperature operated device. The thermostat does not have a control knob and it is factory set to the temperatures required by Hygiene Regulations.
Wash Thermostat Part Number 30201 Function Controls the wash element Description The wash thermostat is a single pole capillary type device. It has a single changeover contact and a rotating shaft for a manual temperature adjustment. Factory default setting is 65°C. Contact switching capacity: 16(4) A 380 V. Diagram Replacement Drain the wash tank. Take note of the connections to the wiring loom before disconnecting.
Solenoid Valve Part Number 3342 Function Controls flow of water into machine during filling of wash tank and final rinsing. Description Electromagnetically operating water valve for use with cold and hot water. Diagram Replacement Disconnect the wires from the solenoid connectors. Remove hot water supply hose. Release a hose clamp on the outlet solenoid hose and remove the hose. Slide the solenoid valve up off the mounting bracket. Replace in reverse order.
Pressure Switch Part Number 600 30308 Function Controls filling of wash tank and protects wash elements. Description The pressure switch is attached to the pressure bell. As the water level in the wash tank rises air is trapped in the bell and increasing pressure is transmitted to the pressure switch. When the tank is full the pressure switch shuts off the fill solenoid valve and switches on the wash element.
Wash Pump Part Number 600 30299 Function Pumps water from the wash tank to the wash arms providing a recirculating wash cycle. Description Electric Pump ZF 320V SX Power: Voltage: Amperes: Capacitor: HP 0.93 Kw 0.68 230 V 50Hz 3.0 A 12.5 uF Speed Protection: Hm Min: Hm Max: 2800 rpm IP 20 1.0 m 12.
Detergent Pump Part Number 600 30094 Function When fitted the pump automatically injects detergent into wash tank during filling of the machine and at the start of each wash cycle. Description Fixed Flow Peristaltic Pump PG1.5 Voltage: Pressure: 230 V 50Hz 0.1 Bar Flow rate: Max suction height: 1.5 L/h (0.42 ml/sec) 1.5 M Diagram Replacement Peristaltic pumps provide reliable and accurate detergent dosing.
Rinse Aid Injector Part Number 600 30324 Function Adjustable flow rate hydraulic rinse pump for rinse-aid chemical dosing Description The injector works by using the water pressure in the rinse line. The pressure in the input line causes the suction of a determined amount of chemical for each cycle. At the end of the cycle a spring injects the chemical in the rinse pipeline. The flow rate is adjustable from 0 to 3cc/pulse. Diagram Adjustment Insert injector inlet pipe into the rinse aid fluid container.
