Hi

I've just taken delivery of my first hottub here in the UK, and am having real problems getting it to cycle continuously.

Its an Infinity Spa / Balboa 500Z interface, and filled it as instructed using the hosepipe through the filter unit with the filter removed. However, I cannt seem to get it to stay out of PR (priming) mode for long at all. I have set the desired temperature to 38 degrees, and it started off yesterday at 18 degress from the tap. After 24 hours its only 27 degrees, and that becuase I have to reset it every hour or so. I can sometimes get it to pass the PR cycle (I think), by putting all the jets on immediately after power is put on, and after the 2 minute temperature measuring cycle it sometimes displays the temperature for a period of a few minutes to about half an hour. Then when I come back to it, the jets have timed off, and it displays PR mode again.

Please can anybody advise how I make the tub get past the priming mode, and heat up properly and remain stable?

FYI its set in Standard mode as well, not economy or sleep.

Finally, there is a "heat" symbol marked on the control panel - its not mentioned in the manual (which is c**p), can anybody please tell me what this is for?
