LX30H THROWS A CODE EO after running awhile. I hit the high reset button under the flaps on the front for both the boost and reg elements . It will work for a couple cycles and then does the same thing....


Machine won't fill or won't fill high enough. site water pressure meets minimum flow pressures. (LX18, LX30 display shows working.
"E0," "E2," "E3," or "E4". LX40 display shows "DR1 PRBLM," "FILL1 PRBLM," FILL2 PRBLM," or "FILL3 PRBLM". Machine will not run.)

1. Low water pressure - check for clogged hose strainer; check that

2. Make sure probes are clean

3. No water pressure - main water supply valves may not be

4. Drain valve open - turn machine OFF to drain machine, then
ON. Repeat twice (this assists in clearing any drain valve
obstructions). Wait for machine to reach READY mode and
press WASH. Slowly open door several seconds later and note
water level. Close door; 30 seconds later, open door slowly and
check that water level is the same as it was. If not, repeat the
OFF-ON procedure. If problem persists, call your local Hobart
Service Office.

5. Delime machine.

Why does the display show "HI" all the time?


This means that either there is a bad high limit switch, or you are getting a bad burn, or the pump is not moving water fast enough. With the power off remove the panel on the side above the plumbing.
There will be a pressure switch seated right on top of the header, then right below that, there are 2 high limit switches (1" round disks) Most typically, the pressure switch will start to leak and currode the contacts of the high limit switch, but some investigating will be necessary.

ROBINAIR 347002K WON'T INJECT OIL


I think you'v try to inject the oil from ''WRONG'' side,as you say RECOVER/VACUUM which is LOW side manifold valve. You should inject the oil from HIGH side ( Turn the high side valve to CHARGE/OIL INJECT after vacuuming & low side vulv to CLOSE possition ) with pressing F1 key. once you press it then hold the key as long as you wish to inject the oil. If you try this way & you still have problem with oil injection then you may need to check oil injection CHECK VALVE or oil injection SOLENOID ( Both located under Hidg side panel mountin valve). NOTE: UV Dye is not a problem for oil injection! I hope this will help you to solve the problem,Good luck. Don't forge to vote for my solution!

Need location of HIGH Gear Pressure Switch on gm transmission


Do you have a 1 piece case or does the bell housing unbolt? A 700R4 usually has 3 switches on the back of the valve body.the one closest to the 1-2 accumulator (pass. side rear corner) is the fourth switch. If you have a two piece case, you have a 4L60E,the pressure switch is still on the valve body but it is an assembly,not a single switch.

My washer starts and the water starts coming in, then it stops and an "F" shows on display and beeps...HEEELLLLPPPPP!!!!


Hi There
I want to say is Merry X-Mas and Happy New Year. I have found what you need hope this will get you in the right direction.
F/H No water detected entering machine or Pressure switch trip not detected.

If after 30 seconds the control does not detect water entering machine and then valves will be turned off and the error code will be displayed.
Or
If the control has turned the water valves on and after 8 minutes the flow meter has detected 10.5 gallons of water passing through it, but has not detected the pressure switch trip, the valves will be turned off and the error code will flash.

Press PAUSE/CANCEL twice to clear the display.
  • If there is no water in the unit:
    1. Make sure that both valves at the water source(s) are turned on all the way.
    2. Check for plugged or kinked inlet hoses or plugged screens in the inlet valves
    3. Verify inlet valve operation
  • If there is water in the unit:
    1. Verify Drain pump operation
    2. Pressure Switch Hose is in good condition and properly connected to Tub and Pressure switch
  • Verify there is not a siphon problem
  • Verify wire harness connections to:Inlet Valves, Pressure Switch, Drain Pump, Flow Meter, and Central Control Unit (CCU)
  • Check all hoses for possible leaks
  • Verify pressure switch operation
  • Verify flow meter operation
  • Verify CCU operati
Thank you for writing to fix ya. Let me know how it went.
