So…my spa emptied out one night and I figured there was some debris keeping my diverter valve open. I remove actuator and pull out the diverter assembly and it looks like this:

So I purchased another diverter valve assembly for $80…and within two days it happens again:

First, anyone know what causes this? The inside of the valve is smooth. Could it be I need to lube up the inside of the 3-way valve? Not sure what to try next. Any guidance appreciated!

Carefully inspect the inside surface of the valve. There must be something there that the diverter is getting caught on. And yes, always lube all o-rings and diverter seals using silicone pool lube.
