undissolved tablets
What tablets is it you’re using?
Where are you so I can gauge the water hardness and what’s the water pressure like?

The tablets are”Ariel” and they were ok up until several weeks ago. The area where I live is in the Central Scotland Region. the pressure is ok. Could it be the temperature of the water? as the ambient temperature has dropped quite a bit, and the machine is a cold fill type.
