Balance Ring

Location: See Front Balance Ring Location and See Rear Balance Ring Location on page 37.

Balance rings contain food grade silicone and several steel ball bearings that counteract unbal-anced loads by shifting the liquid and ball bearings to the opposite side of the unbalance weight.

If a balance ring has leaked, an oily residue can be felt on the wash basket and clothing. Silicone residue can be removed by cleaning with soap and water and running the basket clean cycle. The washer will also make a loud rattling noise and have excessive vibration in spin. It is unlikely that high speed spin can be achieved with a damaged balance ring.

The balance rings are semi-transparent which allows the liquid level to verifi ed as shown below.

Liquid Levelq

It is normal for the tub assembly to move around quite a bit until the ball bearings have become correctly positioned, especially between 150 – 300 rpm. Once the ball bearings are in position the tub assembly movement will lessen greatly.

Balance Ring RemovalThe inner tub must be removed in order to replace the rear balance ring. (See Inner Tub Removal)

The front balance ring can be replaced by removing the front tub only. (See Front Tub Removal.)

To remove the balance ring from the basket and trunnion assembly, remove the six T 20 Torx screws that hold the balance ring in place and pull the balance ring out.

Rotor

Location: See Rotor Location on page 36.

The rotor is the mechanical portion of the motor system that applies rotational force to the wash basket. A series of magnets around the perimeter of the rotor interact with the electromagnetic fi eld created by current fl ow through the stator windings.This interaction causes a pushing and pulling eff ect on the rotor, causing the rotor to rotate.

Rotors are inherently reliable components. Most issues will be related to cracked or missing magnets, a cracked housing or out of roundness.These issues will likely not aff ect washer perfor-mance but will create noisy operation. Inspect magnets and housing and verify rotor is not out of round.

Rotor Removal1. Disconnect power to the unit.2. Remove the rear panel. (See Rear Panel Removal)3. Remove the 1/2” standard thread rotor bolt and

Operating Voltage: 3 Phase DCResistance: 16.6 Ω phase-phaseLocation: See Rotor Location on page 36.

The stator is wound in such a way as to produce three changing electromagnetic fi elds that interact with the magnets of the rotor to produce rotational force. The electromagnetic fi elds are created by passing current through the phase wires. Each current is phased so that its electromagnetic fi eld is opposite polarity of the rotor magnets.

The steam valve part of the water valve assembly is a low fl ow water valve used during steam cycles. Steam is created by heating a small amount of water in the sump.

The fl ow meter is built into the water valve assem-bly and cannot be replaced separately. It is used to monitor fi ll rate and keep a cumulative count of the amount of water that has entered the washer. The fl ow meter consists of a hall senor and water paddle that has 2 embedded magnets. Water fl ow causes the paddle to rotate. As the paddle rotates, the magnets of the paddle interact with the hall senor which generates a pulse train to the IMC board.

Drain Pump Location (Front View)

Recirculation Pump

Drain Pump

Recirculation pump operation is controlled by a relay on the IMC board. Recirculation pump opera-tion is monitored by the IMC through the pressure sensor. Before the recirculation pump starts, the IMC board records the current pressure sensor reading. When the recirculation pump is started, the IMC board looks for the pressure sensor reading to drop slightly. If this drop does not occur, the IMC sets a recirculation pump error code.

Recirculation Pump Tests1. Enter service mode.2. Run Test 26.3. Press the Start key to begin the test.4. The door locks and the cold water valve is turned

on. The control will fi ll to the main water level and then turn off the water valve. When the water level is above the Recirculation Pump Set level, the recirculation pump will operate. If the water level is below the Recirculation Pump Set level, the recirculation pump will turn off .

Recirculation Pump Diagnostics1. Check for current draw at IMC J701-3.

• If current draw is detected and water is not circulating, check for foreign material in pump and pump fi lter.

• If no current draw is detected, go to step 2.2. Check for 120 VAC between IMC J701-3 and IMC

J101-2.• If 120 VAC is not present replace the IMC

board.• If 120 VAC is present check wiring between

IMC board and pump. If wiring is ok replace pump.
