Hi, I'm Bill. I'm here to help you with your question.
Sounds like you have something wrong with the Hydraulic Port Valve that regulates and changes the cleaning zones.
This probably needs to be inspected/repaired/replaced.
1. Inspecting the Port Valve Assembly and filter screen are the first things to do.
2. If the intake filter screen is broken or missing, debris could be inside preventing the cam from moving properly. Clean out any debris and all should work fine, making sure screen is placed back in good condition.
3. Internal Parts could be worn to prevent cam from moving/seating properly. Visual inspection of these will be needed to determine extent of parts needed.
This should solve your issue.
If you need additional help, I would need to know more specifically what Brand and Model Cleaning System you have.
Thanks, Bill
