Wilson SuperX Questions & Answers

Update 31/12/19. Drove from Kelmscott to Shoalwater and reset the top red button again. Had hot water when I left. Found the actual Wilson website and sent them an email regarding the problem. I thought this was their website when I posted my question but now realise this is an independent review website.

Update 31/1/2020. A month later.

Wilson’s phoned me on the long weekend from my message on their website. Said he would check on warranty when the office opened next week. I was impressed at prompt reply.Their serviceman Glen came on the Tuesday which was the first work day after the NewYear holiday. Wilson’s supplied the $30 part free and I paid the call out fee of $154.00. I was happy with the prompt service. The hot water has been working perfectly for the last month so the problem is fixed.

" the tap or valve that feeds cold water into it should be on full" I didn’t advise this. I said the slower the flow the hotter it will be. You could always contact Wilson direct.

Hi Paul, it can be from the flow tap which you’ll have next to the unit. The slower the flow of water the hotter it will be.

Hi Sarah,
If your landlord personally installed it and he is not a licenced electrician then he may have voided the warranty. But if he is, then obviously all complaints about it have to go through him as he is obviously the one who purchased it and must have the receipt. If it had been installed by Wilson's nominated sparky then it owuld have been just a matter of a phone call and you would've been set as they come with a 2-yr warranty. Not much else I can tell you, really. Good luck.

It sounds as if you have a water pressure difference between you r hot and cold pipes. make sure the pressure is the highest possible going into the Wilson (the tap or valve that feeds cold water into it should be on full open), though the unit itself may have some water pressure modulation valve inside it it should not be so restricted as to cause your cold water to take over completely and prevent hot water from coming out.

Do yourself a favour get rid of Wilson and buy a Stiebel SimpleX. Much better easier to install all the plumbing lines up and they look and work great

I have one you just turn the hot water on a little bit til it heats up then turn the tap more after that and add cold

I would immediately contact Wilson to put you onto your area service plumber who should come and fix or replace it since it is under warranty. There isn't much else you can do, I'm afraid. Wilson have a website and if you use their 'contact us' form they are pretty good about replying quickly.
