Dish Machine (Hobart CL44e stuck in final rinse cycle)

[ectofix]

Shut the machine OFF, open the door nearest the unload end, then check to see if there’s a utensil stuck under or behind the final rinse actuator. Look carefully because an errant fork, spoon or knife can be hard to see. If you can’t see anything from that direction, then take a different look by pulling the unload end curtail off.

This is a common problem with that machine’s design. A simple spoon can prevent the final rinse actuator from having a full rang of motion.

Hello, I did look for that first. nothing obstructing the tray switch. actually removed it to see if anything changed. curious if there is a timer possibly failing. also curious if possibly the top sensor and float could cause this. due to red light on board lit for lower sensor but light is out for upper. assuming that is, it’s supposed to be lit once machine is completely filled. can’t find any info on the Hobart circuit board operations.

Yes, the UPPER LED for both tanks should illuminate once the tanks are full. Tank 1 is the rinse tank and tank 2 is the wash tank (I know that sounds contradictory to your thinking, but that is correct since the rinse tank fills first).

So, if the upper LED is NOT illuminating for a particular tank although its upper float is obviously floating against the probe’s stem, then that float switch is probably going bad.

Before calling it bad, though – make sure to inspect the affected (or even ALL) floats. Carefully wipe them and their stems off all around with a dry towel, then try it again. Sometimes some gunk can impede proper mating of the magnet within the float and the Reed switch encased within the stem.

If that doesn’t solve it, then either replace the float…or the whole probe & float assembly.

The new part number (which includes an o-ring) for the whole probe & float assembly is 00-913135-00225 (I recommend just doing that so it’s fixed and you don’t have to mess with it anymore.) If you decide to just replace the float, its part number is 00-122674. If you buy just the float, be sure to get a new o-ring too – part number 00-067500-00072.

I suggest you contact your local Hobart service center to procure the parts.

Correction:

I just realized you have a CL44e, while I was thinking of my CL64e machines the whole time. So I looked YOUR machine up and appears it doesn’t have two tanks (wash & rinse). It just has a single tank (wash). Of coarse, each of those has a FINAL rinse section (which has no recirculating tank).

In your machine, tank 1 will be the wash tank. However, the part numbers I gave you are the same.

Sorry for the confusion.

thank you for clarifying on the probe and LED light on the board. red light on for lower and off for upper. although tank is full. could have went either way with lights. 🙂
thank you for this info. we do have an account with Hobart. will order now. thanks again!

Yes, the lower and upper LEDs should BOTH be illuminated when the tank is full.
