Hi Helen, Great idea this reminder. I was only thinking the other day that I’ll need to get back to you guys for some more stuff as I’m only almost out now due to having my Spa “Off-line” for some time due to a burn-out in the circuit board. As my Spa is an older version I thought I’d have trouble getting parts so I decided to check the circuit board out myself and fixed the problem which was a burnt terminal. I’ve only just this week run the unit and today stepped the temperature up a tad so I’ll be ordering some more stuff soon. Thanks for looking after your customers – if only our FAMILY GP would do the same.
