Bosch SHU 6800 Refill rinse agent light stays on

Within the last few weeks the "Refill Rinse Agent" light came on and the D/W would run its cycle down to 1 minute and just keep running. When I open the door the water is hot but it will not drain. I refilled the rinse agent according to the manual with liquid jet dry and nothing changed. I turned off the power at the breaker and still no change. I put it on rinse and hold and the water drained out. Any thoughts?

    The refill rinse agent has nothing to do with it. I just found out (from my local repairman and this message forum) that it is a bad control board. I wish my husband was a handyman, but had to pay for a new control board. It has to do with a wiring problem that is caused by a burned solder joint.

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.

SOURCE: Bosch Dishwasher Not Draining

Im really not all that familiar with the bosch unit, but a few things i would ck. when you cancel a cycle (it should drain the water) is it humming??? does it sound as if it even trickling into the sink discharge?? do you have a disposer under your sink that this unit drains into, if so remove the clamp and look for possible obstructions right there.Honestly passed this ill have to defer to someone else sorry and good luck

Hello Lynne, welcome to fixya.

I know what the problem is, though you may not like it. I would still start by checking your water inlet temperature, the unit must be connected to a "hot" water supply line. Try running the hot water at your sink tap to insure the cold water is out of the lines just before you turn on the dishwasher.

That is just a suggestion out of courtesy however...

If it is what I suspect, the control, this won't make any difference but it's worth a try. If on the other hand the water is good and hot entering the machine, you likely have an issue with the control as I alluded to.

The reason your dishwasher is displaying a "1" is the control has detected a heating error. It isn't the countdown time. The error code is displayed by the number "1". Here`s the most likely reason why it has detected the error...

Even if your home water supply appears hot, it's not hot enough and must be heated by the dishwasher to insure a proper clean and dry.

The issue with your Bosch dishwasher likely lye`s within`the electronic timer/control, specifically the heater relay solder joint. ( a faulty flow switch, ntc or heater can also cause this, but not very probable ). This is why it runs forever unless pressing the two buttons for "cancel".

To repair your unit It will require you to remove the control from the unit and then remove the control from it`s plastic housing and look for a burnt solder contact on the printed circuit board. This will be one of the pins from the heater relay, hence the unit sit`s at "1" ( because it can`t heat to advance or until canceled ) trying to heat the water.

**Further to this, if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...although Bosch recommend`s replacing the control and I don`t pretend to speak on there behalf nor do I profess to know better. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)**

**Please disconnect the power before attempting any service to the dishwasher. If you do not feel comfortable attempting this service, call a local pro, preferably one familiar with Bosch/Thermador/Gaggenau, to service your machine.**

Hope this answer`s your question's, let me know if I can assist you further. Thank`s for visiting "fixya" for your repair inquiries. Please take a moment and rate this solution to it's helpfulness to you and leave a testimony if you're satisfied.

Good luck.

SOURCE: light appears stating to refill

There is a rinse aid dispenser on the door.

Buy some from your local supermarket, open the dispenser and fill it. Close the lid and the light should disappear.

Rinse agent (blue liquid) is leaking into the bottom of the dishwasher compartment. Every time I refill, it leaks out within a few days. Any idea what is causing this?


There is a lot of info missing like brand and model, but it a general way they all work the same. A preset amount is dispensed in the last rinse cycle by an electric circuit. Sense this appears to leak the entire amount the valve/ opening is not shutting. A repairman would just replace the rinse aid dispenser assembly. They are hard to clean because the are a molded/sealed assembly.

The last few times I filled the rinse dispenser and ran the dishwasher I notice the arrow showing the rinse aid is almost empty. Impossible. What is going on with this?


THE ANSWER IS YES. FROM YOUR DESCRIPTION IT SOUNDS LIKE THE DISPENSER PUMP OR RESERVOIR IS LEAKING. YOU NEED TO REPLACE THE WHOLE SOAP DISPENSER. ALTHOUGH DISH WASHERS NEED THE HELP OF RINSE AID IT IS ONLY DISPENSED A DROP OR TWO AT A TIME DURING THE FINAL RINSE CYCLE PART OF THE WASH. HOPE THIS HELPS AND THANK YOU FOR READING THIS.

No water is coming in and its almost like it is 3/4 of the way through the cycle and stuck in the same position.


If the wash motor continuous to run but the cycle is frozen then most likely the thermostat or heater is faulty. Try to run one of the short cycles like rinse only to confirm if the cycle is completed.

I have a Bosch SHE4AM15UC diswasher. The rinse agent comes out at the gasget. The rinse agent light does not come on anymore windicating it needs more agent.


I would have to say the sensor may be fouled up and need to be cleaned if you are concerned about the light. If the rinse agent is coming out of the gasket I would look for small cracks around the dispenser, then the door panel may need to be replaced.

The Rinsing aid door keeps opening in my Bosch dishwaser


I believe paddy55 is correct about the rack position affecting the rinse agent door. When the top rack is moved to the higher position, the rack hits the latch on the rinse agent door, causing it to pop open.

Move the rack back to the lower position and see if the door stays closed.
