The washer has an error code recall function, to see them you'd need to enter diagnostics. That would be helpful and likely easier than me asking you 4-5 questions.
This is same process for you.
Here it is on paper.
Might be easier to follow. Pg 3 for how to enter. Codes start on Pg 6. Each code is "FxEx" with "x" being a #. The grey/white squares shown with each error are the lights flashing under your knob to ID the error if you do not have a display.
Don't base a repair strictly on a code, they are not all as cut and dry as they seem.
