Beachcomber 350 Jets Wont Turn Off

[sweetspa]

Hi

We've just purchased a Beachcomber 350 and we are having a problem with the jets tonight.  Usually we press the button once for low, twice for high and a third time for off.  However tonight they are not turning off just giving us low or high.  Any suggestions why? 

Many thanks
