I did buy a "BUNN" check valve. It has the barbs. I have not had a chance to use it yet.

As of 10/20/2022 Univen High Temp Food Grade Red Silicone Tubing 8mm ID X 12mm OD is unavailable from Amazon.

Thanks for the information on the hose size. I need to do this again. I'll cut the holes to make it easier to get to the clamps. Thanks again.

Good idea with the gloves. I was not paying attention to fingerprints, I was more concerned about dog hair as I did this on the basement floor.

I slid the display to allow me to lift up on the long edge. Once you get it up a bit, it will come up.

Great idea with the access holes. In the future I’ll use the “red” high temp hoses. The clear tubing sprung a leak after a few months. I MAY have pinched it while installing but either way it was a pain to remove from the heating element. I agree that the “Home Brewing” companies have a good selection of hose.

With these types of coffee makers, 80% of the time the thermal fuse is bad and 20% is leaking hose(s).

The DCC-3200 had a larger inside diameter hose then that of the DCC-2600.

High Temp Silicone Tubing - 3/8 in. seems to be a good fit for this repair. Remember, whatever hose you use make sure it is “high temp” AND “food grade”. The hose needs to fit TIGHT on the fittings. If you can slide it on and off with very little effort, it’s too loose!! Don’t count on the clamps to seal the tube to the fitting. Think of how difficult it is to get the old hose off. It’s on tight for good reason. There is very little to no pressure on these hoses but they need to be liquid tight. Make sure you push the hose onto the fitting as far as it will go. The more tubing that is in contact with the fitting, the better it will seal.

I have no idea if you can get the diffuser anywhere. I’d do a google search OR keep an eye out for a trashed tv at the curb. Good luck.

I would have no idea where to get those parts. Try google?
