Several visits by ‘engineers’ – some parts replaced and as of this afternoon (Wednesday 19th) the water temperature is stubbornly on the cool side, it is around 5/6 °C below what it should be.
Lots of scratching of heads…..after some 2 weeks.
When I was the ‘Engineer’ and something wasn’t fixed pretty pronto – the magic words were pack your bags you’re on the next flight home…..get it ‘fixed’
