THE HEATER UNIT-UPPER PART JOINT LEAKS

I've made sure that I have not cross threaded the upper from the heater unit. I've also been extremely careful with the coffee, so that no ground coffee ended up on any of the threaded edges. I even tried lower heat settings on the electric range in an attempt to reduce the leaking.

Leaks water - not sure where it comes from. Thank


Coffee leaking into the drip tray could be from the brew unit or the front door assembly. Water leaking probably means a hose connection to the boiler has failed. Don't just leave it, fix leaks immediately. Besides the electrical danger, the rust on working parts from long term leaks can be extensive.

Are you confident? Operate the machine with all covers off to see where the leak comes from. Be extremely careful, ready to pull the plug at any moment. Touch nothing inside! Burning, scalding and electrified! Check both boilers very closely while making coffee, most leaks become obvious on close examination.

Most leaks are due to failed o-rings in the connectors at the end of the teflon hoses, usually at the coffee boiler. Replacing the o-rings should stop the leak.

Source replacement o-rings. Slide the hairpin c-clip out of the side of the white connector and pull the teflon hose out. Fish the old o-ring out of the connector with a small hook or point if it didn't come out with the hose. Place the new o-ring over the end of the hose, snug against the brass collar. push the hose back into the coupling being careful to go straight and true so as not to damage the new o-ring. Some force may be required, be careful not to kink the hose. Blunt needle nose pliers to push the rear of the brass collar usually does it. Replace the c-clip and test for further leaks before reassembling.

Hi, DeDietrich automatic coffee machine. "fault on water system" We have had never ending faults with this machine and this was the original fault on the first machine. They just swapped it...


The problem is water leaking from any number of places inside the machine. To access the piping you need to remove the machine from the cabinet, remove the top metal cover (about 9 screws) and then the next metal cover under that (two screws at back). Disconnect power before doing this! Once the covers are off, you can search for leaks. First step is to mop up the water in the bottom of the unit below all the pipes and heater. Use a paper or cloth towel that you can wriggle down past everything to soak up the water. After this, plug the unit back in (keep clear of any live wires!) and you should see fault on water system message is now gone. If not, there is still more water to be soaked up. Now you can watch for leaks when you make a coffee. Most likely they will be from one of three places - first is at the heater unit, second is at the solenoid to the top left of the heater unit and third will be at some clip held plugs further in the machine behind the heater unit. If it is either of the first two, then simply buy a hose clamp (6-9mm hose) from you local hardware and attach near the existing clamp. Easy fix. If it is at the other plugs further in the machine which are held in by hair pin clips, then it will be a slow and not always successful job. Best is to get some new o-rings AND new hair pin clips first. The O rings are silicon (red) and 007 size. Remove the clips, remove the hoses from the socket, remove/ replace the o-rings and reassemble. With luck the leak will be gone. If not, try a little inox food grade grease on the o-rings before reassembly. This can be a frustrating leak to try and stop!!!!!

Brew unit miss


Hi
Open the door on the right. The brew unit is the thing with the handle that has the "press" on it. You need to push on the upper left side of the brew unit until it clicks. There is an outlet spout on the opposite side of where you are pushing. It goes into an intake port that needs to be lubed (food grade only), so the outlet spout will slide in without pushing back. That should take care of the missing brew unit.

Water does not get hot


There are several things that could be causing this - the thermostat, the limit thermostat, or the tank heater itself. You can start checking by unplugging the unit, then remove the screws from the lid. Carefully lift the lid until you can reach the wires going to the top burner. Pull these wires off, placing them where they won't make contact with the metal on the unit. Look inside the unit, and see if there are any wires burnt off. If not, look at the small limit thermostat that is located on the top of the tank. It's a little round white unit. Move it around, and see if it's loose or broken. lift the metal tab, and take the limit thermostat out. Many of these units break apart, and quit working. If it's broken, take the two wires off it, and replace it. If not, then it will probably the thermostat or the tank heater. To see which it is, take the wires off the tank heater -the two poles sticking out of the tank lid. Using a voltmeter, check for resistance across the two poles. There should be resistance there. Also, check for continuance from the heater posts to ground by placing one lead on the heater post, and touch the other to the side or top of the tank. If the needle moves at all, your tank heater is shorting to ground, and needs to be replaced. If these tests are ok, then the main thermostat needs to be replaced. Hope this helps.

Unit heats but water doesn't come out


I had the same problem. I read this article and was able to figure it out the probem: http://home.howstuffworks.com/coffee-maker.htm The one way valve and the heater pipe in the bottom of the unit are extremely calcified. I opened the bottom by removing the four little "security" screws. I used a little tiny flathead screwdriver because I didn't have the proper "star security screwdriver and it worked fine. Next, I removed the two orange hoses and soaked them in white vineager. The shorter intake hose contains the one way valve. make a note of which way you remove this hose 'cause it has to go back in in the same direction. Next I propped the unit on its side so that I could put some vineager in the heater pipe and let it soak in there. Next I blew into and sucked air out of the one way hose and then rinsed both hoses thoroughly. Then I used a little piece of a wire coat hanger to scrape out some of the junk in the heater pipe, (especially on the heat side) followed by a little pipe cleaner to get it extra clean. Then I put it all back together. Be carefull that the hoses are sealed ok. I actually cut a little off of them to get a new seal on the side that connects to the heater pipe. There wasn't much room for error though. After getting it all back together I ran a few full pots through it of 1/2 vineager 1/2 water and then a couple of just water. Probably a good time to change the water filter inside the unit too. Also, from now on I'll make sure to use the self cleaning mode more often. Good luck. Kevin
