I have a hobart dishmachine model# CRS-66AW after filling dishmachine water will not stay in the wash tank, sometimes half of the water drains out. we have replaced the o-rings on the drain plug recently. Any other ideas? Thank You, [email protected]

1. Clogged drain line: The drain line may be clogged with food debris or other debris, causing the water to back up in the machine.
2. Blocked sump: The sump, which is where the water drains into, may be blocked with food debris or other debris, causing the water to back up in the machine.
3. Faulty fill valve: The fill valve may be faulty, causing the water to fill beyond the normal level.
4. Leaking pump or hoses: The pump or hoses may be leaking, causing water to collect under the machine.
5. Broken float switch: The float switch, which is responsible for controlling the water level, may be broken, causing the water level to rise uncontrollably.

It is recommended to have a certified Hobart technician or a professional commercial dishwasher repair service diagnose and repair the issue

Clogged or defective drain valve Clean and/ or replace drain valve, P/N 04113.00

Sounds right. The level may be an issue with fill solenoid rather than tank floats. Also, is the drain overflow blocked?

If it's drain water and filling with water at the same time your drain hose is lower than the water fill line of the washer. try raising the drain hose up higher

make sure all the curtains are there ,also check for any baffles missing from mach. should be 2 1 on incoming side 1 on outgoing, also ck hood vents had problem before with vents wide open sucking heat right out of warewasher

E0 STANDS FOR NO WATER @SUMP PROBE DURING 3 CONC. CYCLES. MY FIRST GUESS WOULD BE THERE IS SOMETHING STUCK IN YOUR DRAIN VALVE ALLOWING ALL THE WATER TO GET PUMPED OUT INSTEAD OF WASHING AND STAYING IN THE TANK. DONT FORGET TO VOTE

it needs to be hooked up to a water supply (hot line).

dont forget the drain.
good luck

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.

THERE SHOULD BE SOME HOOKS AT THE TOP OF THE MACH INSIDE AT BOTH ENDS AND SOMEWHERE IN THE MIDDLE TO SEPERATE THE WASH TANKS AND THE RINSES TANKS, ALSO AT THE ENDS SO THE WATER DOESNT SHOOT OUT ONTO THE FLOOR,THE SPRAYERS COULD EITHER BE THE WASH ARMS OR THE RINSES JETS IF ITS THE ARMS THEY GO IN THE TOP AND THE BOTTOM ONES GO JUST ABOVE THE WATER LINE OR SCRAP TRYS THE BOTH SHOULD LOCK IN SOMEHOW,I IF ITS THE RINSE JETS THE GO IN THE RINSE ARMS WITCH ARE AT THE EXIT END WHERE THE TRAYS COME OUT, THE JETS SHOULD THREAD INTO THE ARMS WICH HAVE PRE DRILELED HOLES FOR THEM.

lift **** basket out and lift out samle stailees plate drain and look for stailess probe coming out of side of tank half way down there should be a white pprobably yellowed plastic ball it is a float they get old and fill fith water and don't flote telling maching I have no water keep the water coming. the float is sometimes even missing fell off andf thrown out. 10 bucks and a clip your off and running. call hobart its 110.00 and your off and running.
