I have a HOBART LXiH, error code E5. This is supposedly a drain issue, yet when turned off, it drains fine. The wash cycle runs fine, then when it should switch to Rinse, the E5 shows.

intermittent contact of pressure switch,
replaced the pressure switch first before you replaced the control board.

the p2 err. is on open or shorted rinse thermistor which is located on the back of the mach next to the vac. brkr. as for draining ck the drain valve for debris, and the end of the drain hose where it connects to the building drain

in this case e5 means too much water in the machine when it is supposed to rinse.

these machines have either a solenoid opperated drain valve or a drain pump.

could be a kinked or pluged drain hose. check this by removing the drain hose (probably red) from the drain it attaches to (probably under a sink)

put the hose in the sink or bucket and wait for it to drain, drain should be fairly powerful (hold the hose and be careful the water is hot)

if the hose is not kinked and little or no water comes out you have likley have an obstructed drain valve or a broken pump or solenoid.

at this point i would call in the pros, or you can try to fix it yourself then curse and wish you had called the pros.

good luck

Try running the drain hose into a bucket next to the machine. If it drains Ok, look for the restriction in your plumbing. If it won't drain into the bucket, look for a closed drain valve, open fill valve, bad middle or top probe, check power at drain connector ( it's DC volts from the bridge rectifier in the top drawer on the relay board.. Basically, water is at top probe at beginning of rinse, or it didn't drain down after the wash. Drain hoses can kink from hot water if not routed well.

tried to take off the drain hose, but could not get it off the back, only by the disposal. I turned if off and on about 6 times and ran the delime cycle with lots of limeaway. It got the E5 error on the delime cycle, but it worked the next time I tried to run it.
The manual does say to turn it off and on as it drains out the water. Takes a while as it has to heat up the water each time.

Does it show a wrench icon and P1?
error codes are p 1to 3 for probe errors, or E1 to 7 for error codes.
P1 is the probe on the wash tank. It's a thermistor with two black wires to a white connector. There is another on the booster front (P2) and a 3rd on the rear airgap, (p3). You could try exchanging 1 and 3 to see if the fault changes too. You have to drain the booster to swap P2. If it can't determine the wash tank temp, it won't know to control the heat and shows the error.

Hi drogers77,

I'm not a Hobart technician, but here what I founded in my manual for the LX30 error message:

LX18 / LX30 display shows E0, E2, E3 or E4

1. Low water pressure - check for clogged hose strainer; check that site water pressure meets minimum flow pressures.

2. Make sure probes are clean

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

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.

Hope it will help you.

E5 is a drain error - machine is not draining - check drain hoses - pull out machine if needed - check air gap. hope this helps. jimmy.

i would clean the 2 back probes with emory cloth and the sump probe underneath the screen.then pour half of cup of c.l.r. (calcium,lime,rust) remover in the dishwasher and run 3 cycles.If you still have this issue let me know.

check the sump probe under the screen and the 2 probes in the right back corner.clean them with a light grit sandpaper.let me know.
