Prevent and fix E02 by descaling a Lay Z Spa Airjet with an EASY-SCALE ™️ kit.

I can’t recommend this enough, it is an essential bit of kit for anyone with a lay-a-spa, not just for descaling but also very useful for testing the pump without having to fill the tub just to test the pump.

I didn't even know this was a thing. thinking about buying a jacuzzi so I'm considering making my own manifold using a 10L ad blue water tank and replacing descaler liquid with either white vinegar or citric acid. Thanks for the insight

[@kelvinsgadgets2557]

There will always be DIY’ers who make their own. No worries there. That said, quite a few of our thousands of customers have given feedback about how versatile our kits are when they have changed their tub, in addition to the cost of the fittings to make their own Our kits (at the time of this post) come with free ABC washers, spare EASY-SCALE coupling washers and sachet of OUST worth over £4. You may want to consider using something a lot smaller than a 10L vessel as this will over-dilute the solution

[@obviouslytwo4u]

@@kelvinsgadgets2557 any chance of making a transparent one that also has a mesh filter in the lower part?. Just to stop any large lumps of limescale or debris being recycled into the pump. If you would think of ideas my thoughts are maybe you could do a rectangle filter the same ID of the vessle with a long stick that you push down to some Mounting points just above lower return aperture.

[@kelvinsgadgets2557]

@@obviouslytwo4u short answer, no. We did consider mocking up something transparent to illustrate our kits working - but it wouldn’t be exactly the same size and shape and thus wouldn’t be a true representation. Our EASY-SCALE’s are made of polypropylene, which - in its natural state is slightly opaque - which defeats what we would be trying to achieve The descaling solution we include tends to change limescale from a solid state to a milky solution. Any fragments or debris is usually collected in the very bottom of the EASY-SCALE as the bottom boss is 2mm from the bottom A descale cycle typically takes 15-30 minutes, once a month, sometimes less frequently dependant upon where the owner lives. This is a very small proportion of total overall running time of a pump We have allowed peoples reviews and endorsements, along with the product itself to show potential customers how it works and how effective it is. People can often get a mis-conception of how good something ACTUALLY is, when all they see is some edited footage Hope this helps

[@W00dsdale]

Hi. This looks great and I will purchase for routine maintenance. However how does it work if the pump won't start at all?

[@kelvinsgadgets2557]

A popular question. Quite a few of our customers have shifted limescale by doing a ‘static descale’ - leave the EASY-SCALE attached and let the Oust work its magic overnight. Try the pump again the next morning. It doesn’t work in all cases but certainly worth a try If that‘s not worked, the chances are it’ll probably be a failed impeller or flow sensor. Don’t fret, both are cheap and fairly easy to replace and certainly not as daunting to replace as you may think. Your EASY-SCALE kit won’t give the kiss of life to a failed impeller or flow sensor but is a very handy tool for testing your pump during and after repairs, aswell as it’s main purpose, a descaling device

[@kelvinsgadgets2557]

Hi. Sorry to hear your’e having trouble. You need to prime the pump by filling with water and tipping back to expel air. If you’ve done that and still getting E02 and it worked before, with no issues, you may have a faulty flow sensor, impeller or a blockage.

Hi. Thanks for your question.

Keep an eye on the water level as some evaporation will take place

Hi Donna. So sorry to hear you are having trouble. Our EASY-SCALE kits are excellent for this type of thing as you can test the pump ‘off the tub’ If you have invested in a kit, attach it to your pump. Remove the bottom panel, split and elevate the pump, fill your EASY-SCALE with water and run the pump.

Hello my friend. This is only my second year with the lay z spa. Just ran it through a cycle for setup and I'm getting no hot water. Tried starting and restarting. Switching the heat on and off but it hasn't worked. I can't hear the thermostat 'click' either when I adjust the heat. My guess is a scaled water heater element. Do you agree? Also, if it is that, can I descale it using your method? Or is it a full replacement jobbie? Thanks in advance for your help.

[@kelvinsgadgets2557]

Hi. Thanks for your interest and question. Answers as follows. Yes, you can descale the heater using an EASY-SCALE. They don’t give the kiss of life to failed parts such as heaters, impellers, etc but are great for testing the pump ‘off the tub’. Could be a failed thermal reset switch, heater control cable / switch (depending on age of the pump) or the heater matrix itself. Another common cause is a frogspawn-like substance caused by using multifunction tabs. An investment in an EASY-SCALE will sort / help diagnose any of these, aswell as it’s main use - a descaling device. Hope this helps

Hi Kevin thanks for the tips. I have a squarish airjet similar to the first one in your video which was only used last year, with a Hawaii square Spa. On connecting it up this year there was a leak from the bottom, on contacting Bestway and sending them a video of the problem they have replaced it under their 2 year guarantee, Any idea what the problem may have been? I have searched KZbin for the disassembly and repairs for this pump model to no avail in case the problem shows itself at again at some future date when out of guarantee. Sadly I can only find fixes for the egg shaped one. cheers John

[@kelvinsgadgets2557]

Hi John Answers to your questions… The pumps are pretty much the same inside. The only significant difference is the necessity to ‘release’ and lift the heater matrix on the newer square one to remove the circulation pump. The screws around the middle are accessible from under the middle section on the new ones too Leaks are soooo much easier to detect by using our EASY-SCALE kits as you can test (run) the pump ‘off the tub’ Take a look at our other KZbin video on how to test the flow sensor.

[@kelvinsgadgets2557]

Hi Stu. Firstly, many thanks for your purchase. A few things to check… 1. Did you replace the impeller with a decent quality one? Some don’t fit properly 2. Did you replace the rubber ends of the impeller? They need to be replaced as they wear and elongate, causing the impeller to knock against the pump casing and fail 3. Did you remove the old rubber ends? Sorry to ask, but you’ll be amazed how many DIY’ers leave the old ones in and crush it with the new one 4. Have you checked the flow sensor? Easy to test - with a fridge magnet (or your old impeller if you still have it). Remove the single screw on the top of the flow sensor housing, remove the short black rod. Attach your pump to your EASY-SCALE kit, activate the pump and put the end of the black rod on a magnet within 1 second of startup 5. Are you using Multifunction tabs? They contain algaecide which causes / creates a frogspawn like substance which blocks the heater matrix 6. Did you reconnect the wire on the internal pump? A very common thing to forget to do when carrying out repairs 7. Have you reinstalled the pump ‘backwards’ i.e flow is in reverse direction
