ASHP systems can't be autosized so you should check the rated heating capacity of the air to water heat pump coil. The default value is designed for a fairly large building (40kW) and you may need to decrease this. I don't think that oversizing will cause this problem though.
Did you use the "ASHP Air to water Heat Pump convector" template? This works for me without modification when applied to the test house that comes with DB.
