Welcome to the forum. With the little info you give I can only guess. First check the winterizing valve on the pump inlet, it may still be in the position to draw antifreeze into the system.

If that is not the problem locate the back of the waterheater and turn the bypass valve handle 1/4 turn either way and see if you have flow. One way will bypass the tank and the other will fill it. If it is in the middle somewhere this may be your problem. (Without knowing the exact model I can not help with the location and how to access the back of the waterheater. )

Let us know what you find. The model number can be found next to the entrance door grab handle in most cases.

If there is antifreeze in the lines and it gets into the waterheater tank you will have to drain it before storage. You will have to winterize everything again after checking the system. Many videos online on how to do it. Good luck.
