OPERATING PROBLEMS

13.1

No Power

If the machine appears dead, and there is no response from pressing the power button, then check
the following.
•
Check the supply voltage and that the machine is plugged in and switched on.
•
Remove the lid and the console.
•
With the power supply isolated, physically check all the plug connections to the Motor Control
Module.
•
With the power supply switched, on check all voltage readings as described in section 6.
•
Prior to replacing a Motor Control Module, check all resistances of the components as
described in section 7. We also recommended that a visual inspection of the motor and pump
area be carried out. Check for corrosion and signs of water leaking as well as damage that
may have occurred to any of the wiring harnesses.
13.2

Flooding / Leaking

•
Check for obvious signs of leaks from taps, inlet hoses, inlet washers, water valves and mixing
chamber. There should be no signs of water within the top-deck area.
•
Check for obvious signs of leaks in the standpipe, drain hose, pump, and air bell. The pump
can leak if the pump bracket is not secured properly.
•
Check that the drain hose is inserted correctly, and that the drain is not blocked, or pushed too
far into the standpipe.
•
Check that the water valves are not jammed on, or dripping when off.
•
Has the pressure tube been connected when the bowl contained water? The pressure tube
must be connected when the bowl is empty, otherwise flooding may occur on the next cycle.
•
Has the machine oversudsed, caused by too much, incorrect use of or poor quality detergents.
•
Has the correct water level been selected for the clothes load? Too much water for the clothes
load will cause water to splash.
•
Check that the size setting of SmartDrive
•
Check that the high water level is acceptable. Acceptable limits are 10-110mm from the top of
the agitator to the water. If it is less than 10mm, then splashing may be a problem. Empty the
bowl, remove then refit the pressure tube to the Motor Control Module, and then retest. If
water levels are outside these limits, replace the Motor Control Module.
•
Otherwise it could be that SmartDrive
detergent could have been used.
13.3

Noisy

If the user is complaining about noise, it may be in a number of different areas. Is the noise during
spin? Is it a banging sound? This would typically be the drain hose, inlet hoses, mains lead or
harness. If it is an out of balance noise, check that the machine is level and stable. Check the
bias spring and balance rings.
specification (Refer Section 1.12).
If it is a 'clunk' that occurs up to 3 times per cycle, this would be a bowl check and is completely
normal. It occurs when SmartDrive
cannot be reduced.
Other things to check are:
• ®
Is SmartDrive level and on all four feet equally.
•
Check the mains lead, inlet hoses and drain hose outside the wrapper, behind SmartDrive
•
Check the harness and drain hose inside is not banging on the wrapper during spin.
•
Check the bias spring is fitted correctly.
•
Check the 2 balance rings in the inner bowl contain water. Check the bowl weight.
•
Check for noisy suspension rods.
