Its A Possibility The Left Over Water In The Hot Is Frozen. If Your Line Is Exposed Outside Somewhere It Can Easily Freeze Up. Turn On The Hot Water Everywhere In The House And If Accessible Check The Lines To See Where The Warmth Ends. You Can Leave One Off Over Night In Hopes That It Will Eventually Defrost.

You need to first make sure is the tankless who do the “up and down”! . If the problem manifest on more then one faucet then the problem is the unit. Have a thermometer (we use a infrared gun wich we train on Hot water pipe !) and see if actually the unit is the culprit.
If the problem is only on one shower It is possible also to be a “antyscalding valve” If the trigger valve on your shower is being adjusted too low then it trigger a splash of cold water now and then on regulate intervals. Try to adjust the temperature lower at the unit (say 110F ) and see if the problem change. If it does, then the problem is for sure in the faucet. If it does not change , then you have a problem with the water flow sensor . It is simply getting stuck. Bad bearing or even a piece of Teflon tape. I believe you will need a certified technician for that so no issues with your warranty will appear.

These units need water flow/pressure to work. If you use a mixer to get the right temperature as soon as you try to increase cold to make the water colder you unfortunately reduce the hot flow. Fairly complicated fault to explain, all continuous flow units have the same flaw. Solution is to try and increase flow and the best way is to take any water filters or restrictors out of your tapware. Most taps have the located in the end of the spout. Unscrew the end and remove any restrictors. Shower roses are a bit more tricky to find. This fixes 99% of these problems.
