Most base Problems on Smart Drive Washing Machines

The First Smart Drive washing machines by Fisher & Paykel came out of output in 1991 and since then we have experienced 8 improved and more sophisticated models. Although they differ a lot, the most common faults are very similar. From our long experience, we can say that approximately 80% of them have minor faults, but are still worth repairing. We will try to cover all of them.If you find that yours is different, it may be some blend of few covered.

No Power

Drive Reviews

This fault can be caused by failure of one of the major electrical parts: motor, pump, rotor positioning sensor, reed switch, display panel or one of the water valves. Also, cause can be in the motor controller itself. It can be burned by water connected short cut or by power surge.

On the “phase 4″( models 085, 058, 508, 608, 708) motor controller there is a mode where it can shut down in the event of a transient on the mains. What does this means is that motor will go in “asleep” mode and the module will not restart unless the power is turned off at the wall for at least 90 seconds.

On the “phase 5” (models 095-Fresh, 059-Pride, 509-Excellence, 609, 709) pump is determined as a part of the power supply. If it is disconnected (thermal cut out tripped which can be caused by pump blockage) washing motor will be dead.

Repair of this fault is quite expensive and vary between models from 0 to 0.

Best way to preclude it is to do regular uncostly service checks of all major parts and empty pockets before wash. If you buy used washing motor try to arrange cleaning, water blasting and sanitizing services which will free drum and bowl from all dirt that can cause pump blockage.

Leaking

This is most common washing motor problem and in some cases it is connected to real technical issues and sometimes to misuse or wrong installation.

Easy to observation leaks are from water taps, inlet hoses, hot or cold water valves, water mixing chamber. Leak from top end of the drain hose is also easy to observation and usual spot is close to the relationship to the body of the machine.

Leaking from the pump is approximately always caused by poorly secured pump bracket; pump’s

diaphragm and pump itself are last causes for the leak. Next possible leak spot is an air bell.

If water level is not set properly and water is filled over High mark on the agitator, splashing may cause some “leak”. Over filling may be caused by bad (dirty or punched) pressure pipe. Clothes overloading can make same problem.

Broken neck ring and damaged plastic inner bowl are other possible reasons for leak as well as too much detergent used.

Fixing of leak connected problems should not(except damaged inner bowl and leak from main seal) be very expensive, up to a 0 most.

Washing motor Is Noisy

Noise can be connected to few separate sources, some of them indicating that motor have to be serviced or repaired to avoid major damage.

If washing motor is very noisy while spin cycle main seal and bearing are bad. This fault has to be fixed urgently, otherwise water leak can damage motor and rotor positioning sensor.

Banging sound is commonly connected to drain hose, inlet hose, mains lead or harness. They are either loose or washing motor has not been leveled properly. This can not cause some other bigger problem but could be very annoying.

Another banging sound can be caused by inner and outer bowl hitting machine’s body.

The reckon for that is that water somehow escaped from two balance rings in the inner bowl. Same problem can be caused by overloading or uneven clothes arrangement in the bowl.

Pump can be source of very annoying noise. This noise starts on the starting of the spray/deep rinse or spin cycle and lasts until pump empties water. It has been caused by rusted pump stator (water or humidity damage) or ex center rotor position. Crc spray will fix the problem temporary and new pump will save motor from more expensive faults(burned pump will burn triac on the motor controller).

Also cracked or chipped rotor magnets can cause some milling noise.

To fix noise problem you may expect anything between to 0.

Washing motor Is “Doing Nothing”

First cause of this fault can be in reed switch(lid and off balance switch). Broken switch should be substituted to avoid motor controller failure.

Water taps can cause this problem also. Water should be connected and taps should be on.

If delay start is on, Strat/Pause switch will not respond.

When Auto Level has been used motor will resense water level every time the lid is opened.

Siphoning

This problem is connected to the natural law. commonly standpipe height is too low. Minimum height should be 850mm from the floor. Top of the drain hose should be placed straight through “U” shaped hose guide not more than 2cm from the top of the guide. If drain hose is pushed too far into the standpipe or drain, washing motor will empty(siphon) water while fill or rinse cycle.

Siphoning can be caused also by restricted drain hose or partial pump blockage.
