PLD4555RFC: Low Rinse Agent Light Will Not Go Out

Just installed a new Frigidaire PLD4555RFC dishwasher. The problem I am having is that the orange Low Rinse Agent light will not go off. The rinse agent is full, in fact we overfilled it a couple times to be sure. I tried turning power on and off and the light is still illuminated. I ran the Water/Service test and did not get an error. However, I did get a message (Lo) at the end of the cycle that the dishwasher still thinks the Rinse Agent needs to be filled.

Any ideas? I will contact Frigidaire as well as the dishwasher is only a week old.

    When our new Frigidaire Model GLD2445RFSO completes a wash cycle, the rinse aid LO code illuminates even though I;ve confirmed that the rinse aid reservoir is full.

    I called Frigidaire and they confirmed that I've done all that I can do to check the problem and I need a service visit..

    An authorized Frigidaire repairman (from local appliance store) came to check the problem. He confirmed that the problem is with the dispenser itself, not the sensor. That is why the unit passed all the checks in the diagnostics test I ran. So, he is ordering a new dispenser and will come back to install it. This is a very rare problem which he has not encountered previously. Good news is that the part should get here quick and everything is under warranty.

I've disconnected the sensor in the dispenser for my new Frigidaire dishwasher. The setup is too unreliable in my opinion and is a potential source of headaches. I had the same problem. I studied the design and it's too easy for the floating magnet sensor in the rinse aid reservoir to stick thereby not actuating what is called a reed switch to toggle the control card LO ckt light. Mine has the electronic control front panel.

SOURCE: Kenmore Ultra Wash rinse agent not draining

I used to think the same in my dishwasher, but come to find out it actually lasts for a few months so it only uses drops at a time..

SOURCE: Rinse agent dispenser

The only "fast" way is to remove the dispenser completely and rinse with warm water until clean! (by removing front panel and then disconnecting jumpers and clips...can be tricky to do alone, as you need 3 hands to pry clips from dispenser to remove from door!) Oshie.

Frigidaire Gallery Series Dishwasher - unit stops near the final rinse cycle without draining - "ER" on front display, all led indicators on front display also lit (e.g. low rinse agent, etc.),...

the problem is within the electronic control. Steam leaks in, due to an improper seal ring. Humidity stay in the compartment and eventually, the contact on the wire ribbon corrodes.
it can also be the new electronic module.
If the electronic module is ok, then the only working solution require that you order and install a "fit kit" from Frigidaire.

Some models even have a recall made form Frigidaire. Better check with them.

Good luck!

I have an Electrolux Dishwasher that always starts on low rinse

Hello Friend, this is Z. Thank you for your post!

I see that your Electrolux dishwasher starts cycle on low rinse. This typically indicates your dishwasher has low rinse aid. The RINISING AGENT LOW light, typically located near the Rinse Only Pad, comes on at the end of cleaning cycle when the rinse agent reservoir is low. The light will remain on through 5 successive cycles or until the reservoir is filled. Also, using rinse aid will enhance dryer performance and reduces water sports and filming. Hope this helps!

Frigidaire Dishwasher Model GLD4355RFS0 Will not sanitize and leaves dishes wet ?

One common issue on these units is the heater wire will fall off. If this happens, the dishwasher will not heat. Also make sure the rinse agent is full. On most of the newer dishwasher rinse agent must be used to help dry the dishes.

Glasses have a film when dishwasher is done.

There are several things that could cause this; 1. The rinse agent dispenser is out of rinse agent(Jet Dry). 2. The dispenser is not working and is easy to replace by removing the four screws that hold the door panel on and the two that removes the dispenser(be sure the breaker is turned-off). 3. The water temperature coming into the unit from the water-heater is not hot enough. 4.Your water may need to be tested for excessive minerals or chemicals. 5. Low grade detergent may not dissolve correctly.

My Frigidaire dishwasher leaks the rinse agent into the tub. Therefore, the low rinse agent light is always on.

it may leak because:
1. Seal is bad. (o-ring?)
2. a spring on mechanism may be loose, missing or broken.
3. the container that holds the fluid may be cracked.

Brand New overflows PLD4555RFC3

If this is new construction or a new disposal, check the hose that drains from the dishwasher to the disposal - the installer may have forgotten to remove the plug when they connected the hose.
