Went tto this machine today. Not made any easier by the fact that all the residents only speak Russian. Customer is saying [I think} that when a normal wash is selected, whether at 40, 60, or 90 degrees, The machine takes about four and a half hours to do the cycle. According to the user manual, a 40 deg wash should take 150 minutes. Customer says heater is working, and a meter check shows heater is OK. Both sol valves work, and machine fills and empties at a normal rate. There are no odd lights coming on. I am stuck as to what to do next . Any ideas please?
