Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
First do you have the new control board ? If not then you need to get with a supply house that sales Manitowoc parts. Now if you have a board or have bought one the here goes. Looking at left top corner of board there is a AC Line voltage electrical plug ( numbers marked on wires ) There is only one that will plug into it. Under that there is a main fuse (7A) then under that is a Automatic Cleaning system (AUCS) accessory plug you wont use it. Under that is the ice thickness probe (3/16 ) connection Marker 1C check water thickness probe and follow wire back to end and plug it to 1C. Now under that one is a spade marked 1F that is the Water level probe terminal go to water level switch in sump tray and find the wire that goes to it and put on 1F. Under water level spade is another spade marked 1G this on is not used on this model. At the left side bottom of board is another plug in this is the DC low voltage electrical plug the numbers are marked on the wires that plug into it there is only one plug that will plug into it.
not sure how much a wiring diagram will help. but you should check continuity across your pump (if this circuit is not closed the machine will not power on). if you replaced a fuse on the board, it is possible that more faults on the board have occured (there are two fuses on the newer model boards)

I understand that you need to rewire your pressure washer. I understand that you already have the switch wired and the motor wired as they are working. You need to power the pump that has a white (common) male and a black (hot) female. You what spade connections do you have open to connect too.
You should have a black and a white that have nothing attached to them this is where the pump wires are going to attache in the circuit.
FdL means that the main circuit board (CCU) is not communicating with the door lock and the door needs to be locked b/4 the washer will work. The door lock is rarely the problem. Most often its cold solder joints on the CCU circuit board causing the bad communication. Many times a F11 code comes along with the FdL code. To repair this problem the CCU circuit board needs to be removed and the solder points where the spade connectors and the relays are connected to the circuit board need to be soldered over again. This all stems from poor quality control when the circuit boards had the components soldered to them. The process was able to adhere the smaller connections but not the larger ones compleatly. If your not to handy with a soldering gun you could take this response and show it to a good appliance repair outlet and they should be able to repair your circuit board. Good Luck.
Usually their is a tech sheet under the motor shroud it should have a wiring diagram. If not the power cord has three leads Black some models use Blue ( Hot ), White ( Neutral ), Green (Ground ). The Black will have the on/off reset switch or on/off circuit breaker to Motor Control Board spade labeled black or blue.
The white lead may go straight to the motor control board spade labeled white. Just follow the wire color s and match them. Good Luck!
There are three wires on the base of the motor, Red, Brown and White.
The White conects to the double violets on a conector
The Red to one side of the capacitor (side nearest the motor)
The brown one caused a lot of confusion. I believe this attached both to the yellow connection and then onto the spade connection on the other side of the capacitor.
This is one I slept on, and had an Epiphany.
The circuit diagrams didn't apear too clear to me. They don't sem to indicate which connections go to the capacitor, just the pump cluster as a group. I may be wrong, but have connected as above and will get the father-in-law to check them before I plug the machine back in.
