Zena... make sure your water outlet hose is as flat as possible... a 'uphill' hose can trap garbage not washed away. Remove that hose and inspect both ends for clogs?

The E2 code is a water supply error. The water inlet valve has stopped working. Try going here... appliancepartspros.com with the model # and you can look up the part and how to put it in. Tis not hard. A phillips & flat blade screwdriver and some pliers.

Hi, F2 means that the Main Control Board is not getting the right signal from the user interface, turn off the power to the machine & then go to you tube there are several videos showing the correct way to remove the screws to give you access to the inner door liner to check all the contacts are clean & connected properly, as if this doesn't correct it then the user interface is probably the cause as it is most likely faulty & needs to be replaced, but to be sure I would follow the step by step tutorial on you tube for your make & model....

I hope this helps....

Replace the heating element. It isn't seeing temp rise in set time

Wash pump could be faulty, the arms could be blocked

That seems to me to be normal unless you have a "Quick wash" cycle that you can select.
