Try pulling it again and make sure that the paddlewheel is centered in the slot. If it rubs against the side, it could give an error. You can use a drift pin to push out the paddlewheel pin and clean everything up, then reassemble. Make sure the cups face the right direction on reassembly.

I pull the paddlewheel and put in the blanking plug whenever the boat is tied up, so never need to worry about cleaning the paddlewheel.
