audiomacgyver OK had a read through
I find it odd that so many pumps have failed, the chances of that are more than 1 in a million. 3 pumps in a row. The magnets went weak because of the type of magnet they are…if they weren’t potted correctly the magnetic material corroded on contact with air and lost it’s magnetism. FOT who make the pumps couldn’t tell by looking at the magnets which were right and which were not…they did change the supplier/process to prevent this recurring. Unfortunately loads of pumps were in the system and took perhaps some years to work through the inventory. They all should have gone years ago, of course there is the chance the odd few remain out there. The feature is the pump gradually hits a lower and lower pressure and ends up making 3 to 5 bar…rarely do they fade to nothing. If the magnet is correctly potted, they should last the life of the pump.
audiomacgyver I have purchased a new pump magnet, but do not have failure analysis to tell me that the issue is with the magnet.
Just to be crystal clear here, you have purchased a new magnet, have you fitted it, does the problem of low pressure remain, make sure the machine is set to a constant 9 bar profile for these checks?
It is possible if the magnet was old stock that you could have put in a magnet with old potting, that has already lost power, remember I said that there could be some magnets still floating around. I also don’t think need to pay for them as Fluid O Tech were supplying a free magnet (and presumably fresh) to people with this problem via retailers
audiomacgyver Fill Time Error
First occurrence in June 2022. After ~ 99 seconds of powering on machine shows “Fill Time Error”.
As in the advanced setting, if for any reason the pump:
- Cannot fill the boiler, you will get a fill time error,
- Low on water in the main tank, can cause a fill error
- The Machine is plumbed, the switch in the plumbed position and the boiler is filling for too long, then it closes the solenoid (anti flood)
You need to check these systems and connections.
audiomacgyver Rust on Access Panel
There is a little bit of rust on the bottom of the machine, the previous owner had a small undetected leak in the machine, I only see issues on the frame.
It’s 304 stainless, so rust will be from something that isn’t or can be susceptible to surface rusting…a screw, a nut, some component, or a weld, because the surface layer of the weld material changes. Clean it off and if any rust remains on welds, brush a line of that treatment that turns rust black on it and forget about it…it’s only on the surface and won’t come back..
Find out where the leaks are, I don’t know if it’s possible they could have got into the pumps electronics? I don’t believe so, but worth checking.
You can speak on a vid you know to indicate where you think the leak is coming from. 🤣
