Section 3

Theory of Operation

Starting the Machine

The door lock will not allow a cycle to be started until the door has been closed.

Fill

The operator selects a cycle and starts the machine. Water enters the machine through water valves that are controlled by the microcomputer. As water fills the basket, a column of air is trapped in a pressure bulb and hose. The air pressure continues to increase as the basket fills with water. When the desired water level is reached, the water level switch triggers the microcomputer and the water valves turn off.

A vacuum breaker installed in the inlet plumbing prevents the backflow of water.

Supply

The operator can either connect external liquid supplies to the machine or fill the supply dispenser with liquid or dry supplies. The supply dispenser's nozzles flush the compartments with water at the appropriate times throughout a cycle.

Drain

Cabinet Hardmount washer-extractors use a normally open gravity-type drain system. No pump is used. When the drain valve opens, the perforated basket allows water to drain from it.

In the event of a power failure, the drain valve will open automatically and the machine will drain.

Extract

A final high-speed extract step removes water from the load, which maximizes drying efficiency.

The door lock system will not allow the door to be opened until the cycle has finished.

Wash

The basket includes ribs that lift the laundry from the wash water. The laundry then tumbles back into the bath.

In 2-speed and variable-speed models, 1 dual-speed motor drives the basket's shaft with a V-belt. In 3speed models, 2 motors drive the basket's cylinder with a V-belt.

18-60 pound capacity models use 2 bearings that are held in place by a single cast-iron trunnion that is bolted to the frame. 80 and 125-pound capacity models use 2 flange-type bearing that are bolted to the frame.

With the machine running, the basket turning and the “ON” light (i.e., the light on the control panel by the timer cycle indicator light) lit, the machine does not fill up (i.e., the water inlet valves do not turn on).

Note: Before proceeding to the next step, take voltage readings across the VN2 (neutral) wire where it connects to the VN2 cold fill valve and input connector J9-3-3 and also across input connector J9-3-3 and input connector J9-3-1*. This is a test to check if the VN2 (neutral) circuit is intact all of the way to all water valves. This will also test the function of the voltmeter. If 120 or 220 Volts** are present on both readings, continue to the next troubleshooting step. If 120 or 220 Volts** are not present on both readings, contact Alliance Laundry Systems’ Customer Service department for assistance in locating the broken circuit.

*Note: All voltage readings should be taken from input connector J9-3-1 as a neutral point. **Note: All voltage readings are approximate.

19. Water Running Continuously with Machine Power Off

Water Running Continuously With Machine Power Off

With electrical power removed from the machine, water is running continuously into compartment 1 of the supply dispenser.

Using the “Water Running Continuously” illustration, follow the hose from compartment 1 of the supply dispenser back through the vacuum breaker and the Y-connector to the hot water valve at V9 and the cold water valve at V10.

To determine which of the valves is leaking, turn off the water supply to each of the valves, one valve at a time. When the water supply is removed from the leaking valve, the water running into compartment 1 of the supply dispenser will stop.

For example, if water is running into compartment 1 of the supply dispenser continuously, when the water supply is removed from the hot water valve, the water continues to run into compartment 1. However, when the water supply is removed from the cold water valve, the water running into compartment 1 stops. Therefore, the cold water valve is the leaking valve.

With electrical power removed from the machine, water is running continuously into compartment 2 of the supply dispenser.

Using the “Water Running Continuously” illustration, follow the hose from compartment 2 of the supply dispenser back through the vacuum breaker to the cold water valve at V4.

Install a valve repair kit onto the cold water valve or replace the valve. Refer to the Parts manual for your washer-extractor for valve and valve repair kit part numbers.

With electrical power removed from the machine, water is running continuously into compartment 3 of the supply dispenser.

Using the “Water Running Continuously” illustration, follow

e from compartment 3 of

the hos the supply dispenser back through the vacuum breaker to the cold water valve at V5.

Install a valve repair kit onto the hot water valve or replace the valve. Refer to the Parts manual for your washer-extractor for valve and valve repair kit part numbers.

With electrical power removed from the machine, water is running continuously into the bottom of the washer-extractor.

To determine which of the

s is leaking, turn off the

valve water supply to each of the valves, one valve at a time. When the water supply is removed from the leaking valve, the water running into the bottom of the washer-extractor will stop.

For example, when the water supply is removed from the hot water valve at V1, the water continues to run into the bottom of the washer-extractor. However, when the water supply is removed from the cold water valve at V2, the water running into the bottom of the washerextractor stops. Therefore, the cold water valve at V2 is the leaking valve.

Once the leaking valve(s) has been determined, install a valve repair kit onto the leaking valve or replace the leaking valve. Refer to the Parts manual for your washer-extractor for valve and valve repair kit part numbers.

Once the leaking valve(s) has been determined, install a valve repair kit onto the leaking valve port or replace the entire leaking valve. Refer to the Parts manual for your washer-extractor for valve and valve repair kit part numbers.
