Er:10 shows up on Nexxt front-loaders when the readings from the inlet flow meter make no sense to the control. That meter is a tiny turbine fitted in the water inlet; it counts what enters the machine, so the washer measures water taken instead of guessing from valve time. Bosch's documentation lists the meter itself or its wiring as the reasons.
1. Close both supply taps. 2. Unscrew the two inlet hoses at the tap end, with a towel beneath to catch drips. 3. Look into each hose coupling for the small mesh screen and rinse it under a faucet until it is clear of grit. 4. Reattach the hoses hand-tight plus a quarter turn and reopen the taps.
A small turbine spins as water passes and the control counts the spins. If those counts look impossible, it stops the fill rather than risk an overflow.
Grit and scale can lodge in the turbine and slow it. Screens catch most of it, but over time some particles reach the meter. Cleaning the screens helps, but a worn turbine still needs a technician.
No. Without a reliable water count the control may overfill or underfill, so it stops the cycle. Cleaning the hose screens is safe to try, but anything beyond that is best left to a technician.
A technician diagnoses it on site and gives you the price in writing before any work starts.
