Hobart LXIC under counter comerical dishwasher. Delime lled keeps comeing on every time power up. Checked sensors on bottom in the water drain area senser on right (there are 2 next to each other on this unit I think other is water temp) the wire had wire burn completely off. I reconnected the wire and started to burn up the wire again. Question: 1) Is this sensor for the Delime sensor? 2) does it sond like the sensor is shorted to you? or sending wrong voltage to sensor? 3) If not the sensor what causes it to go in delime mode every time starts up?

Hi!

You need to buy a calcium lime remover/lime remover and if you can see a bad lime deposit then please buy a stronger delime.You need to put the delime in the unit and run it through a cycle.Repaet this procedure more than once to get optimum results & get rid of the scale. Also try and delime it once in a month or two so that this doesn't happen in future.

Please rate this solution.

Thanks

Hold the delime button in and hit the on button for 5 seconds.It will then do a partial fill then it will say add delime,add delime shut the door and press the wash button.Let the machine do the rest it will turn itself off when finished.

SOURCE: what product to delime the Hobart LXi ?

Ppur a full cup of apple cider vinegar into the empty dishwasher and run it for the full cycle. Then run it again with nothing in it. This will delime your machine beautifully.

To reset or clear delime message, on control board there are 3 buttons. from power off, drawer open, manget on door switch, door closed, hold PROG on board and press the ON key on keyboard. pressing select moves to next poption, up arrow increases setting. step through select until you see delime, settings for LXi are de for disabled, and 1 through 65= x100 cycles. rg if set at 5, after 500 cycles the message apears. To keep the settings and clear the message a delime sequence needs to be run precisely as described.

DO NOT MIX DELIME ACID, RINSE AGENTS OR OTHER ACID WITH BLEACH PRODUCTS, OR HAZAEDOUS GASES WILL FORM.

With machine off, remove rack , close door, press and hold wash/delime key and press ON. Delime will be lit on display, release wash/delime key, and let machine fill. you should then see ADD and DELIME on the display, open the door and add the delime agent following supplier's instructions precisely. close the door, press wash, delime will flash. After delime is complete power is turned off. Inspect the machine and repeat if necessary.
DO NOT LEAVE THE ACID IN ANY LONGER THAN RECOMMEDED.

The machine is trying to tell you to delime it. After a certain number of wash cycles, the LXI dishwasher reminds you to run a delime cycle (instructions are on a label on the bottom of the dishwasher). Judging from your posting, it's been ignored for quite some time, so you may need to run multiple delime cycles, depending on how much scale is built up inside the machine on the probes, wash arms, rinse arms, drain body (though you can't see this part, heavy scale deposits will cause draining problems). So . . . . get some good strong delimer and run a few delime cycles (talk to your chemical supplier about delimer - don't buy some weak stuff like LIME-A-WAY off the shelf).

Once you've delimed the machine, your E4 code may go away. E4 is the dishwasher's way of telling you that it did not fill properly on the initial fill (when you first turn on the machine). More specifically, it means the dishwasher DID NOT SENSE WATER at the upper probe at the rear right of the tank (there are two probes back there, on one assembly, referred to as the MIDDLE and UPPER water level probes). The probe may be coated with lime causing difficulty sensing water at the probe, so a good deliming may clean the probe and fix the E4 problem (in fact, reach back to the probes and break off any heavy built-up lime/scale deposits before deliming). If the E4 code persists after deliming, watch the pressure gauge on the front of the dishwasher. If the gauge reads lower than the green area, you need to adjust or replace the water pressure regulator. If the E4 problem still persists, replace the probe assembly at the rear of the dishwasher.
