Squeal in head

[OlygirlNav]

Has anybody had a squeal in the head when flushing? If yes, how did you resolve?
We have Tecma EasyFit Premium Plus on R29 2020. The joker valve has already been replaced. We only use marine TP and seat cover is down when not in use. This occurs when head has not been flushed in a few days. After first flush then goes away until next time sitting unused for a few days.
I have replacement motor pump on hand if necessary to replace. Does not look like fun task or easy to do. Any tips on replacing?

We saw this tug while we were on the dock in the Swinomish Channel yesterday. It took us about 20 seconds to realize that we looked liked idiots waving and hollering to the smiling but perplexed people with your ex.

Seems like squeal was due to TP stuck in pump area which over time dissolved. After that the pump was twice as loud as before when flushing and sounded different. Changing out the pump was the fix. Now the head flushes quietly. Freya Marine LLC in Bellingham was able to replace the pump in a little over a hour.
