We purchased a used motorhome with a Splendide washer/dryer combo. We wanted to try the dry cycle. The door lock light and dryer light come on, but nothing happens. I hear a click sound, like it wants to start, but doesn't. Also, the door does not lock. Should it lock when on the dryer setting? We haven't tried the wash cycle yet.

I have exactly the same issue. The door normally locks, but doesn't do anything on wash.

SOURCE: Splendide 2100 no longer dries clothes

We had the same problem with our splendide 2100 top loader. If you remove the top cover, you will find 2 circular like black discs (the size of a dime) on the right hand side about 6 inches from the front. You need to push those down (with a very small blunt object) to reset them. Please make sure that you unplug your washer/dryer before you attempt this. Good luck.

Your heating element could be out. This could be just a bad element or if you don't hear the fan come in the the dry cycle, the fan probably failed and caused the element to burn out. If your clothes are getting warm but not drying completely then you need to check your exhaust hose and make sure it is not clogged with lint.

SOURCE: Most recently, the dryer function is not drying

Run a cycle with the Dryer vent hose off. If the clothes come out dry, you need to have a duct cleaning company come out and vacuum out the duct.

Remove the top - two screws in the back then slide forward
In the front right top you will see the air box and the terminals for the heater coil along with other wires and sensors. Start the washer on a dry cycle and check the voltage to the heater terminals. You will be looking for 120 AC. If voltage there but no heat the heating element is bad. If no voltage there follow the wires to the overheat switches and check the voltage on the other side of these switches (round devices with two terminals on top). If there is voltage there then the switch has tripped. Unplug the machine. Look for a spot of paint on this switch, scratch it away and you will see a small hole. Insert a strightened paper clip into this hole and push to reset the switch. Re-power and test the results.
No power to these switches probably means a bad circuit board $$$.
