STEP-BY-STEP INSTRUCTIONS. 1.) Measure the pipes. Starting at the water heater, measure lengths of insulation needed to cover all accessible hot water pipes, especially the first 3 feet of pipe from the water heater. It's also a good idea to insulate the cold-water inlet pipes for the first 3 feet.
I'll be helping you with your problem today. F11 means that your main central control board (CCU) and the motor control board (MCU) are not communicating with one another properly. The motor control board is located under the tub mounted to the floor of the washer.The CCU is mounted under the top panel of the washer and is the part with about 100 wires going into it. You'll want to remove the top panel and the lower front panel to check the wire connections and make sure they are all secure.he motor control board is located under the tub mounted to the floor of the washer.

I have checked what I believe is the fuse for the wipers and washer (same fuse for both). In my 95 YJ, the fuse is different than the rest, it has a metal cap over the plastic piece that typically tells you the amperage. I have swapped the fuse out with another 20 amp fuse, and no change.ried to use my 98 TJ's wipers for the first time today. The wipers work fine, but no washer. When I got home, I turned the engine off, turned on wipers and tried to make the washer spray but nada. Full reservoir, but no pump noise. Tubes look ok.
