That doesn't sound over the top to me at all. In fact, it's pretty standard at a lot of airbnbs as far as I am aware. Also, the dishes are mentioned in your house rules which the guests are agreeing to when they booked. It's hardly fair for them to then complain afterwards.
This is the problem though with cleaning fees. Some guests are going to resent being asked to do anything at all if they are paying one.
However, in my experience, most people would leave dirty dishes behind nor be offended at being asked to wash them or other simple tasks like putting towels in a hamper. So, unless your cleaning fee is very high, I wouldn't worry about it too much going forward.
Perhaps you could word it in a way that explains to guests that there is a logical reason why you are asking them to do these things, rather than being a 'lazy' host, e.g.
"The listing is cleaned thoroughly in between stays, but please help us avoid pests and smells by washing your dishes, taking out your trash and putting used towels in the hamper."
I don't know, perhaps other hosts will disagree on the above wording. I do not charge a cleaning fee nor do I ask guests to take out trash or do anything specific with the towels, but I'm a homeshare host, so that is different, as I can keep on top of things like the trash. I do ask guests to do their own dishes or put them in the dishwasher and leave communal spaces clean and tidy though. I've never had anyone complain that this is 'over the top'.
I did get a low rating recently though from a guest who had to be reminded a couple of times to do this. He didn't mention it in the review, but I am sure that was the real reason behind his low ratings. It's very rare that I have to remind guests to wash their dishes and not block the kitchen sink!
