I have a Hobart LXi H under counter comm. dishwasher. How do I get the delime icon to go away? It is always on and blinking. Thank you.

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: https://feg.hobartcorp.com/CookieAuth.dll?GetLogon?curl=Z2FresourcecenterZ2Fdefault.aspx&reason=0&formdir=2 . The direct link is: hobart.co.kr/install_pdf/040.pdf .

I hope this helps.

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.

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.

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.

tried to take off the drain hose, but could not get it off the back, only by the disposal. I turned if off and on about 6 times and ran the delime cycle with lots of limeaway. It got the E5 error on the delime cycle, but it worked the next time I tried to run it.
The manual does say to turn it off and on as it drains out the water. Takes a while as it has to heat up the water each time.

What is your model?Lxi,Lx30h?

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.

With the unit off----hold the wash/delime button in and hold the on button in for 5 seconds.the dishwasher will fill and the delime icon will be on,then it will prompt you to add delime,add the delime and hit the wash button.It will run for 5 minutes,fill up twice and drain twice then turns off.

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.

You will need a delimer. This is typically a liquid chemical purchased from your chemical supplier. Personally, I like Lime-Away from Ecolab
