DeLime light and detergents not flowing into dishwasher

The DeLime light will not disappear even after I have a solution to cure this problem thru the dishwasher. Also it will not draw detergent or rinse agent. We have checked the lines and they are not plugged. We also are using the recommended detergent for this dishwasher.

Use a commercial deliming agent (like Lime Away or LSR). Remove the rack from the dishwasher and close the door. Press Off to power down the machine. Next press and hold Wash (Delime) while pressing ON. Delime should show in the display. The unit will fill with water and then flash Add and Delime. Open the door and add the deliming agent according to the directions. (The sump holds about 3 gallons of water.) Close the door and press Wash (Delime). The machine will start the wash mode for 5 minutes and then do two rinse and drain cycles. Delime symbol will flash while this takes place. When finished, the power to the control will be turned off. Check the interior of the machine for lime deposits. If needed, repeat the delime cycle. If the delime program is interrupted before it is completed, then start the delime process from the beginning.

The manuals and other documents are available to registered users of the Hobart site here: . The direct link is: .

I hope this helps.

Hobart commercial under the counter diswasher LXIC Model Number 130016. DELIME light comes on every day at startup. Machine will immediatly run (in DELIME mode I think) for about 5-10 min and then get E4...

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.

How much delime agent should I use to clean the system in a Hobart LXI-H?

Depending on how often you delime the dishwasher use 2 cups.The delime light will come on after 1000 cycles set from factory default.If the delime icon is lit and beeps,turn the unit off.

Push and hold the delime/wash button and on button for 5 seconds and youll be in delime mode.

The unit will fill and heat up and display "add delime".Open the door add the delime and press the wash button.The dishwasher will run for 5 minutes then rinse and drain twice then shut off.When you turn it back on the delime icon will be gone.I'm a hobart tech and repair these dishwasher often,any questions let me know and please rate me,Thanks.

The hobart lxih is stuck in delime.

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.


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.

Dishwasher says delime on screen, how do i do this?.


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.

E4 indicates water level has not reached top water sensor. Check for proper flow-water pressure to machine (15-25psi) and clean sensor in wash tank
