I have a error code low flow switch error. I emptied the tub and refilled it. So the code is still there. Check for air locks etc from everything I read. Also it is not heating up at all.. Also where you put the filter there is a cover that goes up and down in the water .. It is not going down and I don’t feel any water being sucked into the hole. Is it because the flow switch error.. that probably is not making the water get sucked down to the filter hole…
Hope this make sense
