The Sharp e1 problem is a timer that is pretending to demand that you clean the filter. It stops the machine every 720 hours and forces you to do a procedure to get it to go away.
There are 2 possible procedures.
1) Unplug the machine. Hold down the power button while you plug the machine in and wait for a beep about 5 seconds long. Let go of the power button. Unplug the machine. Plug it back in.
2) Unplug the machine. Hold down the mode button while plugging the machine back in and waiting for a beep of about 3 seconds duration. Let go of the mode button. The machine will start. Turn the machine off by pressing the power button. Resume trying to use the machine normally.
If these don't work, the "demand to clean filter" timer is broken and you will need to buy parts to repair the machine.
