Front load washers....

Found mystery E70 trouble code. Its not listed in manual but its a cold water supply issue. I read up on the control valve and they tested ok so I looked at the strainer screens in the inlet fittings and the cold water one as FUBAR with a bunch of mineral deposits plugging the screen about 50%. You don't have to remove the inlet valve assembly (blue thing under the top cover, 2 screws) to clean the inlet screens, just use some needle nose pliers and gently pull out the 2 screen caps inside the inlet. They are tight but will come out if you work them side to side and pull on them evenly. Back flush them with compressed air or CLR and a pick if the nuggets are embedded and push back in. Mine flowed visibly better on COLD setting and the wife told me the warm setting was still rather hot when she took the clothes out so that should have been a red flag to me telling me the cold water supply was faulty.
