What is the method of removing the hot and cold soleniod ?

Power off at wall and pull the plug out. Remove both hoses from inlet valves. Open the panel. Pull all the wiring plugs out of the control box (they only go back in the same place as they are all different sizes) Remove control box (Have a towel ready because some water will come out as it is water cooled) Remove 2 screws at back of water valves & remove the holding clip. Remove one screw holding water chamber down & then pull chamber plus both valves up & out. Remove faulty valve & swap the rubber seal over to the new one. Refit in reverse order. Run machine & check inside the panel for leaks before screwing panel in place. Most important because you will blow the control board if it gets wet.

Here's a YouTube video showing how to do it.

Not the same machine but the concept will be similar.

Take off the top cover and look to see where the water pipes come into the machine...
