The drum turns slowly during washing rotation. 1. Check that the drive belt is tight and that the adjustment screw for motor suspension is screwed tight. The washer does not empty. 1. Be sure the drain hose is not blocked or kinked. 2. Check the drain pump and pin trap. 3. Check the level switch. (See page 13.) 4. Check the programmer (W600/W620) or the motor control board (W640/W660). (See the schematic diagrams for measuring points.) Metallic sounds are heard from the rear of the machine. 1. This could be the brushes in the main motor. Remove the rear cover plate and investigate the cause. The programmer does not work (W600 and W620). 1. Make sure the power to the machine is on. 2. Check the fuses. 3. Check that the programmer motor runs. The machine does not fill with water. 1. Make sure the power to the machine is on. 2. Check that the water valve is open. 3. Be sure the Delay Start has not been engaged. 4. Check for error messages (W640/W660). 5. Measure the voltage at the inlet valve and the outputs from the program control board. (See page 14.) 6. The maximum fill time is five minutes. If the unit hasn't filled in five minutes, W600/W620 will advance to "C" on the Program Control knob. W640/W660 will display an error message. 7. Check the level switch and its hose. (See page 13.) 8. Check the level sensor. (See page 13.) The machine continues to fill up with water and the program stands still. 1. Switch off the power to the machine. If the washer still continues to fill, the valve is stuck. In this case, turn the water off immediately. Remove and clean the valve. Be sure to flush the water feed line. Also, clean the filter thoroughly. Before reassembling, inspect the washers in the fill hose. FAULT TRACING 2. Check the level switch and its hose. Be sure the small hose to and from the "Y" pipe is not blocked or cracked. 3. Check the level sensor (See page 13.) The machine does not pump water out. 1. Make sure the power to the machine is on. 2. Be sure the drain hose is not blocked or kinked. 3. Check the voltage and continuity (see page 13 for these values). 4. Make sure the pump rotor in the drain pump moves freely. (See page 55 for instructions on emptying water from the drain pump.) The machine vibrates more than usual during spin drying. 1. Make sure the shipping supports have been removed. (See page 3.) 2. Make sure the machine is level and the locking nuts on the feet are secure. 3. Make sure the flooring beneath the unit is solid. If it isn't, place a 3/4" to 1" thick piece of plywood under the washer to strengthen the floor. 4. Check the shock absorbers for signs of corrosion. Foam in the last rinse, water remains in the machine. 1. Check the type of detergent used and the amount. (See the ASKO Use and Care Guide.) 2. Check that the drain hose is not blocked or kinked. 3. Check to see if the drain pump is blocked. Water leaks 1. Too much foam can cause a small puddle on the front left side of the machine. 2. Check the hoses and door seal for signs of wear. 3. Make sure nothing is caught in the door, such as apron strings, shoe laces, etc. Too much foam 1. Use only low-sudsing detergent. 2. Try using less detergent. Use only one to three tablespoons (as stated in the ASKO Use and Care Guide.) Unit stops in the middle of a program It is normal for the machine to "pause" during a program, especially between cycles and during the Wool wash program. 11
