Jura z7 error message empty coffee tray when tray s not full

I need the full model number of the water heater to pull the manual on it for you.... so far only an error code 61 is shown. sometimes a 6 can look like a 5 on a digital display if it's a 6 then error code 61 is bad fan motor or printed circuit board that sends power to the fan motor.Get me the full model number, we can go from there

Just a wild guess but......Empty/drain the condenser. Look for a petcock or other faucet type fixture on the condenser.

call a factory service tech to reset your filter changer mechanism

That error means that it is sensing an OVERLOAD. If it does this when it is empty, then there is something causing the error. IT could be something stuck in the drum around the seal or the bearing or it could be the bearings itself

Water heater is not 100% identified.
Unknown if this is gas or electric heater.

Problem posted under Whirlpool water heaters typically made by American water heater company.
Call Whirlpool 877-817-6750.
They will ask for model number and serial number located on label on side of tank.
Call is answered in USA by trained person who can answer specifics about that model, including warranty, age, regular maintenance, error codes, and possible solution for that specific model and serial number.
I have found these folks to be helpful.

Whirlpool manuals do not show that specific model:

If you have the energy smart electric water heater with electronic control board, then error code explanation shows on the control board. Error 1 or a single flash, is start-up failure and requires tank to be full of water. Read page 10 of manual. Make sure water heater is full of water and water is coming full stream out of tub spout before turning on power. Also disconnect power from unit, make sure water heater is full, and then reconnect power to see if unit resets.

DSi light coming on is to alert you that the water heater didn't light on propane for one reason or another. Sometimes people just forgot to turn propane on or are out of propane. What happens when you shut it off and turn it back on? (listening and watching from outside with cover open) DO you see or hear sparking?

As far as black water showing full when just emptied, it is most likely a piece of toilet paper inside the tank that is hanging up from top probe on inside of tank, and touching lower probe, thus giving a full reading. This is very common, at all levels. You can buy a rinse wand and rinse inside of tank through toilet to try and wash it off, or live with it for now, and add lots of water or cleaner deodorizer to tank , or buy probe cleaner, or even the old standby, some laundry soap added to tank , then fill tank close to full with water and rock trailer to swish it around, then drain it. Most times, waiting until next dump, and adding lots of water beforehand, will fix it.

1/ check overheat stat 2/ check fan esp the little hose at the fan area for pinhole best of luck

The tank was full of water . The blatter in the tank was empty so I pumped six pounds of air into it and it works great.
