Malber WD1000 wont condense the water that is fed through during the drying cycle
Since it drains properly during the wash cycle, we know the drain pump and its impeller (propeller) work, and the coin trap (you called it a filter) and hoses are not clogged. By the way, turning the rightmost knob to "4" will start the pump-out cycle, so you don't have to open that trap-door at the bottom. To condense, the machine needs COLD water (spritzing on an internal screen) during drying. Make sure your cold water hose is connected to the outside (outboard) connection on the back of the machine. As a long shot: If the gray drain hose is pushed too far down into your home's drain pipe (more than 8") there could be a "back-siphon" where dirty water siphons back into the washer. It's a long shot, but it does happen.
Lastly, the controller board (mounted at top of right side) could be bad, and not sending on-off commands to the pump during drying. During drying, the drain pump should cycle on and off constantly, every few minutes. Do you hear it running? If you remove back (about 12 Torx screws), at your lower left you will see the pump. There are only 2 wires (120 VAC) and they can be connected either way. Stick a meter on the terminals and see if power is cycling on and off. If not, the controller board is bad.
You can order one from Malber (in NYC) by calling Nancy at 516-323-5299. Tell her Mike, in Wash. D.C., says hi.
