Just wanted to double check about this one as water matrix is close to £100. Machine is pouring water out of the top overflow of matrix. The top left seems quite clogged, I had the bright idea of blowing down the overflow and it popped the plastic film on the back of the matrix and gushed water out (I don’t recommend this)I’ve re sealed it. The machine is not very old so I’m not sure I’m on the right track or not.
Well got it working but in the end I had to drill an 8mm hole around the top left, insert a tube and blow water through blockage. The grot stuff did not work as well as i’d hoped. Re sealed hole with wet grab (i love it almost as much as WD40)
