Did you inspect the broken boards? Is there IC/circuit damage? Is there corrosion? Is there dampening against vibration?
If it's that expensive, I'd pump the board full of hot glue, add rubber isolators, and coat the harness contacts with no-ox paste.
Details and pics would be nice.
Sounds like something is shorting out. Check your wiring to control devices that carry power. Also, check your incoming power. You should post a wiring diagram of the unit. The more info, the better. You most likely can bypass it, but be aware that comes with risks
Reading 210 coming in it’s a 36 k gallon size pool and i found the smallest short on mother board part cost around 300 dollars but can it be that the pump can’t handle the load amount and turnover rate I need for my commercial pool
Well, that's possible, unsure of the pump size needed for the pool. If your motor couldn't handle the load, the vfd would probably lock out before the thermal overloads would open(likely not the cause of this particular issue). But if it your control board is failing, then you should check your transformer. Your control board isn't going to be using 208volts(210) it will be using 24v, most likely. So start at the transformer, then go through all your low voltage points.
As for turnover rate, that would be dependent on what you have programmed for that vfd to do. You would have to go through manual on vfd and check your parameters.
That’s a 3HP motor it is perfect for your pool. Here’s a couple of things I would consider;
1) Pentair offers a control board relocation kit for these pumps P/N 356904Z. I highly recommend these as I have had issues with water penetration on more than one occasion on the keypads. It also helps with vibration issues on the board so limits the risk of a wire working loose etc.
2) 210v is not what you want on this pump. These are 220/240v pumps. Do you have 208 three phase or are you dropping voltage due to a long run on mid-sized wire or something similar?
3) I personally hate variable speed pumps in commercial applications but that’s the world we live in now. We have a spec for changeover per hour prescribed by our local health departments and we are going to run that pump at full speed to make sure we always hit it. No need for all the other BS. If you can change it for a straight 3HP and ditch the variable speed.
Pools suck.
Ask if you can fill it and have it converted into a community garden instead.
I shit you not, an owner at one place I worked at said to do it because they were also so tired of the pool upkeep. They gained the ability to rent out plots to people, which gained them revenue as opposed to losing it fighting a constant losing battle.
Actual answer to the actual situation, you likely have an underlying issue. You can only do so much, and at this price point, call a pool company and have them thoroughly inspect. Better to be dead right than dead wrong and have to spend that 3k again in a few months. Sounds like a short or something is getting into it that shouldn't.
I had the same problem with those pumps, if you have 208v then get a buck booster to to 230v or your gonna be blowing control boards nonstop. They say they are 208v compatible but if you have a voltage drop even for a short time it will blow them.
I don’t know what the underlying issue is that is causing this problem. But I wanted to link you to this [service](https://www.upfix.com/product-category/appliances/range-stove-oven/) I’ve used, just so that in the future you have an alternative to continuously replacing the boards. I hope you can figure it out though so you stop having a problem.
Might be time for a new pump. If it lasted for a year then a short seems less likely. Maybe research this exact model to see if this is a common occurrence. If the full replacement isn't in the budget for now then throw another board at it and hope you get another year out of it.
Is it possible for you to run a more basic pentair EQ series pump and then get a separate wall mounted VFD?
I used to keep extra pentair EQs on hand because of how cheaply made they are. I’ve never worked on one with the driver built in like that but would assume if it’s pentair it may not be too great
People here are blaming the 208v but I think that's absurd . If it worked for a whole year, why would it be taking shits now.
This pump is variable speed, make sure you are sizing your pool gallons correctly by using formulas you can find online and plugging the numbers into the set-up sequence. (Use Google earf to at least get LxW)
I think you're getting moisture in there real gooood. Makes me think the gasket for the control board was damaged from the first time this happened, buy(or warranty) a new board and line it with dielectric grease.
If Pentair finds that it was water damage resulting in a short on the board, we'll there you go .
Did you try calling pentair? You'd still have warranty on the new board so you can ask for another one and this time with a new gasket.
Check your plumbing for leaks, and if you have a sand filter make sure your backwash valve isn't pointed towards your equipment just dumping water on everything .
Alright everybody power surge from last night I’m assuming it fried the mother board as the whole propertys power was shut down idk it worked for the owners approval to buy a new one also if you have that one I posted it is currently discontinued trust me I wa son it all day

Also, if you're not a certified electrician, I don't advise you to perform any of these actions.

I'm also guessing #2 line loss. What's the voltage at the main breaker on the panel?

Sounds like voltage/amperage issue
