Section 4 Troubleshooting 4. WATER RUNS CONTINUOUSLY INTO THE WASHER-EXTRACTOR (Either when the machine is in cycle or not) Note: This information applies to the four main fill valves as well as the 4-way supply valves. The first task in this process is to determine which valve is staying on. If it is one of the four main valves (i.e., hot spray, hot fill, cold spray or cold fill), this may be done by individually shutting off the water supply to each valve.
