My tray is empty and clean but empty tray keeps coming up

1. Thoroughly clean the small overflow area in the drip tray. Once the drip tray gets full water flows over a small rim into this small separate part thus triggering the sensor that tells that the drip tray should be emptied. Its waals may get a bit fatty/dirty, and so remains wet and keeps triggering the sensor.

I experienced the problem with a hotpoint TCYM 750, with the red empty water light failing to switch off. After removing the filter and cleaning it, cleaning the condenser and drying anywhere I had access to the machine still didn't heat and the light remained on. Reading the post about the machine having 3 reservoirs it struck me that one of the reservoirs may be hard to access. So I unplugged the machine and tipped it onto its front. The reservoir drained, I pushed the machine back upright and cleared up some water around the condenser. The drier now works properly and the empty water light is off - job done!

Hi all, I have the exactly same problem on my Gaggenau CM470 however the drip tray is clean and the contacts in the back is also 100% clean.. I wonder if its possible to disable the sensor/switch on a CM470 ?

Miele CVA 4066 -Empty drip tray warning would not go off even after draining the drip tray, cleaning contacts, and resetting power. Water was coming out from under the empty tray.
I pulled unit out and removed sheet metal in rear around water inlet. when I attached water line and power cord & turned on power, I could see water dripping out of one of the 2 solonoids on the water inlet valve. $168.00 from Miele and no expensive service call.

try taking the tray out and leaving it out for like 2 hours with the machine still in the on position. mine has done this before, when i reinsert the tray it will go back to select coffee on the menu. FYI - there is like a built in timer for the tray removal - I believe it will tell you what the timing is in the booklet - howver it works best to do what is stated above.

Open the preground coffee lid, drop a cleaning tablet in it, let it do it's tablet cleaning cycle. After cycle empty water out of tray and clean.

aye that is true if you click the coffe making button directly after you have had it out you will be able to make a cup, as the machine has a 2 second response time.

Ok here is what i think:
As it registers the driptray I dont think its the sensor to it.
More i would think that its the CPU card that is not responding to that its clean.

I am sry but I have to ask this:
When it says emptie the driptray are you actually taking out the container that is located under the brewing unit, and not the "drip tray" were you put the coffe mugs?

Also when i think i have a sensor problem I allways take out everything. Brewing unit, dripwater container, dregbox, and the watercontainer. and have it out for atleast 2 minutes ( clean it under the mean time) and put it back again.

As I dont have the machine infront of me i cant be certain:)

The solution was referenced in one of the earlier postings but I wanted to clarify in case people are misunderstanding. The two metal contacts at the back of the machine insert into the wall of the machine and tell the coffee maker that the tray is inserted. Sometimes the big, flat, readily visible portion of these contacts get dirty and I think people are focusing on this portion of the contacts. However, the metal contacts also bend down into the tray where they can detect water (basically if there is enough water or material to conduct between the two contacts then the machine tells you to empty the try). This is the portion where you need to focus on cleaning, down in the tray, between the narrow plastic valley at the back of the tray. It will require Q-tips or something to really push down into the tray to clean away from the contacts. I did not have water in the tray but had enough moist old coffee grounds that it was causing the issue. I cleaned this area with water, a toothbrush and Q-tips and ensured it was very clean and dry. I have not seen the issue again in months (my coffee maker is three years old, gets used daily and we keep it relatively clean, but this is the first time we've gotten this error).
