I also get an issue where the DHW preheat doesn’t work while the pump is doing it’s running on business. This also wasn’t an issue on the old firmware.

Mine does exactly the same! It stopped doing it when they replaced the wave and it was on firmware 02.18.02 Started playing up again as soon as the firmware updated to 02.19.01. If I turn the temp down enough it stops running on and my hot water preheat is fine again. I’ve had the pump...
