VIBRATION SENSOR ERROR
Cause
The vibration sensor is damaged or has experienced excessive vibration.
Solution
Check for loose connections at vibration sensor and Main PCB and possible damage to harness.
Check for 5Vdc on Red to Black wires.
DETAILS BELOW:
uS or u5 Error Code (Front Load Washer)
- Have the shipping bolts been removed?
- Is the floor stable and level where the unit is in the home?
- Was the unit leveled correctly when installed?
- Is the unit installed on a pedestal? Make sure the pedestal is level with legs as short as possible. The unit should be leveled to the pedestal with the legs as short as possible. Make sure all the screws (16) are in place that attaches the washer and pedestal together. Make sure the leg locking nuts are tight.
- Is the customer loading the unit properly? Run a rinse and spin cycle with 6–8 bath towels and check the unit operation. If the unit runs normal, have the customer bring samples of the loads they have experienced an issue with and see if they are loading unlike materials together. Provide the customer education on proper loading of the machine.
- Remove the front panel. Are all tub weights mounted to the unit and bolts tight?
- Does the tub appear to lean or droop to one side? Make sure the paint on the tub springs are the same color and are installed properly. Inspect the struts for damage and rust on the shaft.
- Does the inner tub have excess side to side or up and down movement? If so, inspect the spider assembly and tub bearings for failure.
FROM THE MAIN BOARD
CHECK FOR 5VDC
BLACK WIRE (-) TO RED WIRE (+)
If you do not have 5Vdc with the unit powered on then replace the main board.
If you have 5Vdc at the main board then check for 5Vdc on the white connector of the sensor cable. The harness at the main board connects to the harness that comes with the sensor.
Either harness could have an issue with a defective wire or a bent pin or connector not firmly connected.

I have a U5 error code and everything checks ok, so replaced the main control and out of balance sensor. It still kicks up new code right away in a drain and spin (within a minute), what else can cause this error code ??
replace the wire harness due to instant sensor errors is due to open circuit or no voltage feedback to the main board

I need the part number for the vibration sensor. Model number WKE 100 HVA.
You need to double check for your product code but the common on for that model is EBD48922821.
I have come across this a few times and it’s usually “was working great and it’s been happening more frequently”. So in that case where it’s most likely not the sensor or the board or the harness, it is the connector coming apart during spin cycle just enough to kill power to the sensor and throw the code. You can simply put a zip tie around the connector and then verify it’s good by doing a rine and spin with 6-8 towels. If it’s the sensor or board or harness then it’ll throw the code despite thus modification.
Thanx a lot ,it helped few times,its connector indeed.
Good information / but what’s the part #
It can vary by model. Please use the parts system for lookup.
Very good helpfuf
Very good helpful
I need the original sensor EBD48922806
Sub # EBD48922821 not working.
If there is a replacement part number that means the original part subs to the new number and the old part number is no longer available.
Very good helf
what is the resitence value?
Our unit measures 2.5MΩ BK to RD, but this is not a reliable way to test this component. Instead, check for 5Vdc coming from the PCB. You can also check continuity on the other wires to confirm. If the PCB is supplying voltage, replace the sensor.
