This washing machine starts to fill then while continuing to fill a E29 error is displayed. After 30 seconds to a minute the error message goes off and the wash time is displayed. The w/m continues to wash correctly.
This has happened in the last 3 or 4 weeks.
For 6 months the customer uses Persil non-bio liquid and Dettol laundry cleanser in every wash and Calgon in every second wash.
It does create a lot of foam.
Anyone had a E29 error?
