Hobart lx30 E3 error

It seem that the machine isn't filling enough to hit the probes required. It might be that it's draining at the same time or something...

Error Code E3 relates to a problem with the fill. Specifically that the water level has not been recognized at the middle water sensor. This can be caused by a problem with the drain system as you describe, or by low water pressure to the machine (should be 15-25psi flow), or bad wire connection to this middle sensor.
Check for proper water pressure first (should be a gauge on the machine) during the fill. Then check / repair drain as needed. These will probably eliminate the problem

SOURCE: dishmachine won't fill

Your problem is as straightforward as your observation, the unit is not getting enough water flow.

First, if your DW water is hooked up with a braided stainless hose, there is usually a screen in the end of it, (check both ends). It gets clogged with debris and chokes off the water. Make sure the line is not kinked.

If that doesn't work, you are likely having trouble with your fill valve. It is under the front kick panel. It has a large castle like upper cap. It is common for debris in the water to make this valve malfunction. It isn't too difficult to open up without removing. Just watch how it is assembled. If you pay attention, it's easy. If you have a booster, the hoses are very brittle with age.

And otherwise, the fill valve may be bad. REMEMBER, verify your supply water flow where it connects to the machine first. Don't assume. You could have a pressure regulator or a line strainer that is part of your supply line. They do fail. But that's a plumber's fix, not a technician.

I use this dishwasher in a florist to clean wax out of candle glass and recently it is not working. E4 codes appear, and it over flows sometimes.


this all I can find Machine will not fill or will not fill high enough. (Display shows E0, E2, E3 or E4. Machine will not run). 1. Low water pressure - check for clogged hose strainer; ensure the site water pressure meets minimum flow pressures. 2. Make sure probes are clean. (See Cleaning.) 3. No water pressure - main water supply valves may not be working. 4. Anti-siphon valve - located in the lower left area of the chamber just above the water line. Drain the machine and insert toothpick or similar object into hole to verify ball (3?16" OD) is free to float. 5. Delime machine perhaps the wax is plugging up the floating ball area

Gene, I have a Kenmore Elite model # 665


Hey Steve,Sorry it took me so long to answer i was offline and my add is not supposed to displayed when i am off line so sorry about that.
Now then on that dishwasher with the hum and no water circulation it sounds as if the main wash motor is jammed up for some reason it could be that the motor itself is defective or as simple as something such a piece of debris such as broken glass or almost anything caught in the motor causing it to not turn on,by disassembling the wash motor you can see if something is caught in,if nothing is caught in its a (sorry to say) the motor itself thats bad and would need to replaced.The reason the water drains even though it will not circulate is because of the separate drain pump that is working Please reply back after disassembling the pump to check for debris if ya need further assistance.
Thanks for using Fixya.Com,GENE

The dishwasher is stuck on drain, I think it has something to do with the overflow. Can you help? Thanks. I have checked all out lets & water in & filters.


Hi

The issue seems to be with the float switch assembly that is bad and should be replaced. Float assembly is found inside the dishwasher's tub, on the bottom. The water that fills the dishwasher lifts the float, and when it reaches a certain level, it acts as a trigger for the float switch. The float triggers the float switch to shut off, thereby shutting off the flow of water into the dishwasher. A defective switch may interfere with dishwasher's filling and/or draining ability. Use voltmeter to test the switch. Set the device to the ohms setting x 1. Take each probe and touch them to one switch terminal each. This should produce a reading of either zero or infinity. Continue to touch the probes to the terminals, and press down on the switch's button. The reading should change to the opposite extreme. If the switch fails either of these tests, you should replace it. Hope this helps...please post back for further assistance.

When turning on dishwasher it just fills the base with water, tried manually draining and pressing reset buttons to no avail


Most dishwashers kick on a valve to fill with water.
There's a float in there somewhere that triggers the shut off to the filling water.
Once water reaches this cut off level the pump should be throwing water thru the wash arms.

If base isn't filling to capacity...Id look to the drain valve.
If it fills to capacity and stops...the pump may be out or something is obstructing it.

Hope this helps...

E5 everytime we run the wash


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.

Leaks water from bottom of door. Error code E7 ?


I found this and it also may have to do with the door seals...how old is the unit...if door seals get old and stiff..(not soft and pliable) they sometimes leak...after usage the heat and moisture may cause them to swell and or become soft thereby sealing better...but this is what I found in the user manual.

Machine displays "E7" on LX30 model or "CLEAN PROBE" on LX40 model.
1. Clean water sensors inside tank.
It suggests contacting Hobart if this fails but I also found this problem is associated with fill issues...as in an E4 error...this what you do in that case....

Machine won't fill or won't fill high enough(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.
5. Delime machine.

Good Luck and I hope this helps...let me know if it doesn't and i am sure I can get to the bottom of it...thanks for rating my effort...the Fang.
