Not familiar with that particular unit, but some units have a float switch in the trap of the drain plumbing (to protect against condensate overflow). Upon a blockage the switch cuts off power to the unit. This switch can be bypassed, at least for testing if you don't have an ohmmeter. If there is a switch, just remove from the switch from the circuit and connect back the wires without the switch. switches are connected in series, power goes in one end and comes out the other.

Clean the drain bucket and reset it.

The E3 error code, indicates that the water in the collection tank is full and needs to be emptied.
Turn the unit OFF & unplug it, before attempting to drain the tank. Once that is completed, the unit should operate as designed.

Yes, there should be a screw out plug for the drain hole on the lower left. If the plug is not in there, the you will have water all over the floor. Unless, you can find the drain cap for it. The auto drain hose connection is about 6" above the manual drain hole, I just mentioned. That is where the auto drain hose connect. It's held in place by a squeeze clamp, that goes on the hose before making the connection. But, keep in mind, with out the drain hole screw in plug, water will still spill onto the floor.

If you can't find it, try Appliance Factory Parts 1-800-955-7075. As they may can help you.

I have the same exact problem, did you ever find a solution?

see if you can push water from the other end to see if you have something that stuck inside

you have a switch for drain if no water coming then try to push water in to get any dirt out

There is a little hole about one inch above the the drain tube and out of it should come a rubber strap connected to a plug for the drain tube. On the far left of the control panel is a diagram of a bucket under a water drop, just below is an led that comes on when the water tank is full and needs to be emptied. I just roll mine out on the porch and pull the plug. Also, when the tank is full the unit should shut off.

Either put it over a drain or, stick a cork in it.
