Error code e01


do the following steps: God bless you
To start test program, press and hold both POWER SCRUB PLUS and RINSE & HOLD program buttons, then turn unit on by pressing ON/OFF button. When program buttons are released, lights above them will flash. To end test program, press ON/OFF button.To check program indicator lights (POWER SCRUB PLUS, REGULAR WASH and RINSE & HOLD), press and hold each program button. When REGULAR WASH program button is pressed, CLEAN light also comes on.
To start testing, press both POWER SCRUB PLUS and RINSE & HOLD buttons a second time. When testing has ended and a fault was detected, the following indicator lights will be lit:
POWER SCRUB PLUS = Heater fault
REGULAR WASH = Water filling fault (over or under filling)
RINSE & HOLD = NTC (temperature sensor) fault ? note circulation motor stops shortly after it started during an NTC fault
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil, measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), REGULAR WASH light will come on and unit will continually fill and drain where testing won't be completed. If flow switch (e5) has failed (opened), water won't heat (to 150?F) and water won?t stop circulating. If NTC probe (f2/f4) has failed (opened), RINSE & HOLD light will come on immediately and testing will end shortly after water has started circulating.
If more than one fault occurs, more than one light will be lit.

Unplug the tower and press power button for 60 seconds, if this fails the motherboard should be suspect, check all plugin connections to the motherboard especially power supply connectors.

My Compaq Presario F756nr will not turn on. The blue light to the power cord is on and blue light on front of laptop is orange but when you press the power on button it comes on then goes right off.


Hold the Power button and at the same time attempt to continually press the button for the CD/DVD drive. Continue until the status lights for power, hard drive and power button stay on for 3 seconds or longer. When status lights remain on, remove your finger from power button and allow the machine to boot as usual. Enjoy.

TV won"t stay on turns off in 3 seconds WS 55807


Do the self check when power light goes off.

On front of set press and hold both the menu and input buttons for 5 seconds or longer and release both buttons.

Power light will blink a error code like: 2 blinks, 2 blinks, a pause and repeat about 4 more times.

Let me know what error code you find and I will tell you what it means.

If this information told you something rate this solution as very helpful as I do this here for free.

I have an Optima Model EP719 Projector. Suddenly I am getting white vertical lines and can't find a solution for removing them.


I would try switching out the DVI cable first. It could be faulty. This would be the easiest and cheapest solution to check.
