Um, you forgot a MAJOR detail; there is a ball valve backflow preventer in the existing hose, which MUST be transferred into the replacement hose.
If it is not replaced, the coffe machine will NOT WORK. - You are welcome.
Nice Ken, very nice….Thank you!!
Where can I purchase the hoses?
Also, the measurements for the hose ID and OD are incorrect. The ID is at least 10 mm. I tried using the measurements you gave, which translate to 8mm ID x 12 mm OD, and that is way too small. The check valve will NOT fit into this smaller diameter tubing. The check valve body itself is 10mm in diameter. I ordered some of the size you listed and it is easily seen without measuring that the tubing doesn't come close to matching.
Oh My....I don't understand Mr. Fixya's numbers to begin with. So, not 10mm or 12mm. can you tell me what mm these should be and possibly where I could find them? My beautiful CHW-12....is now at an insane $185. What a blessing to hear that this can be repaired! thankyou soooo much xo
