WTW8120HC0 PIC

The Whirlpool WTW8120HC series of top load washers is a newer version of their revamped top-loaders with excellent features. 

I like the new, more robust drive system best about this series of washers. Long ago are the days of the floating basket that presented so many problems that Whirlpool had to make some design changes quickly. 

But, Whirlpool did what Whirlpool does. They respond and retool their designs with better technology and even better performance. One of the machines that came out of a years-long brainstorming session is our model under discussion today. 

They refined this new machine, as you can see from the picture, and inside, the changes in how the cycles intelligently work their way to the finish are nothing short of impressive. Compared to other machines supposedly in the same league, this machine comes out on top in every category. 

I’m going through the most common error codes you see in the field more often than the others. One thing I want to stress is that this model doesn’t have silly problems overlooked in the design phase. 

Any problem is usually minor and easily fixed, assuming you’re a dedicated DIYer like all Neli readers! You can book an appointment here. Whatever the problem with your appliance, we’ll help you every step of the way. 

Accessing the Service Mode

To enter Service Mode, press the ‘Select/Enter’ key (Key 2) located on the upper right of the display in the figure below:

Entering Service Mode 1

NOTE: The layout shown above doesn’t show labels per the HMI (user interface) keys. The name of each key may vary with model. The relative position to the screen identifies the key’s function.

NAVIGATION
Use ‘Left’ and ‘Right’ keys to step through pages. When the desired screen is reached, press ‘Select/Enter’ to enter into this screen or activate the action. Use the ‘Back/Exit’ key to return to the previous screen or cancel an action.

When the desired screen is reached, press ‘Select/Enter’ to enter into this screen or activate the action. Use the ‘Back/Exit’ key to return to the previous screen or cancel an action. 

EXITING SERVICE MODE 

To exit from Service Mode back to customer operation, there are two options:

1. Navigate to the ‘Exit Service Mode’ screen from Service Mode.
2. Repeatedly press the ‘Back/Exit’ button until the screen returns to customer operation mode.

 

Fault/Error Code Display Method 

Fault codes are displayed in the format F# E#. The F# indicates the suspect System/Category. The E# indicates the suspect Component system. Up to four Fault/Error codes may be stored. 

Active Fault Code Display in Service Test Mode

During any Service Mode operation, a fault could occur. Depending on the specific fault, the display may show the active fault code. Only one active fault code can be displayed at a time. All fault codes will be recorded in “Fault History”. 

Clear Fault History
To clear stored fault codes, enter Service Mode, then Fault History. Use the ‘Left’ and ‘Right’ keys to navigate to ‘Clear Fault History’. Press the ‘Select/ Enter’ key to clear all faults.

Service and Fault Codes header

F0E2 – Oversuds
Fault is displayed when suds prevent the basket from spinning up to speed or the pressure sensor detects rising suds level. The main control will flush water in an attempt to clear suds. If the water flush is unable to correct the problem, this may indicate:

 

  1. Not using HE detergent.

  4. Mechanical friction on drive mechanism or basket (items between basket and tub).

 

F0E3 – Overload
Fault is displayed when the main control detects a load size that exceeds the washer’s capacity OR basket cannot be turned. This may signify: 

 

  1. Load size exceeds washer capacity. Remove excess laundry, then restart the cycle. 
  2. Mechanical friction on drive mechanism or basket (items between basket and tub).

  1. Check for weak suspension. Basket should not bounce up and down more than once when pushed. 
  2. Items should be distributed evenly when loading.

 

F0E9 – OB Pause
Fault is displayed when an off-balance condition is detected and after user interventions.
 

  1. Check for weak suspension. Basket should not bounce up and down more than once when pushed. 
  2. Items should be distributed evenly when loading.

 

F1E1 – Main Control (ACU) Fault
