Rinnai combi E110C

For the past 4 weeks my own Combi will deliver a sudden momentary cold blast of cold water while in the shower. Lasts for maybe 1 minute then hot again and good, not fun! Can't figure it out doesn't seem to have loss of gas or water pressure. Not sure if it is through out the house or just this shower. Might check the shower valve but I doubt that is the problem. Clean the boiler with vinegar yearly. Crazy.

    Any error codes? How long do you have hot water before this happens? What shower valve is it?

    Have good hot water 4 minutes before it starts and not all the time. No error codes. Symmons

    You may very well want to swap out the spindle inside the valve. They do get junked up.
