It is possibly coming from the heat exchanger. Most heaters have a copper tube style exchanger, capped at each end by plastic or metal headers. If the tubing has been subjected to any corrosive water condition such as low PH, low calcium hardness or very high cyanuric acid levels, the tubing may have deteriorated and is leaking. You may have dismantle the heater further and check for leaking.

Black water pours out of the heater system into intex spa

Backwash filter system, change filter media if over two years old, flush out heater. Check water clarity going into the filter system, if dirty..., you may have a broken underground line. Check water clarity coming out of filter system, if dirty.., backwash again and check filter media. Also, Heater boiler headers may be rotting.

My spa throws the breaker at the house when the heater kicks on

For whatever reason, looks like water has gotten in to the heater or heater controls. To prevent a fire, this must be taken apart and repaired. Be blessed.

Lay z spa pump has E02 code which is water flow problem,have changed filter.flushed through ,set reset button but fault code still appears.

If this is an outdoor spa near trees, its almost a guarantee that the impeller is blocked with debris (pine needles can cause this in a hurry)

If the impeller is clean of debris and this is still happening, replace you pressure/flow switch.

Water is pouring out of the side of our boiler in the pump room

More than likely, this would the result of the heat exchanger being corroded (rusted) and having a hole in it. Depending on the model of heater that you have (you did not specify in your question) this exchanger may be replaced, but for the most part, due to the cost of the replacement, it may be best to replace the heater altogether.
There is not a whole lot in a heater that would cause water to pour out. Most older units deteriorate over time due to chemical damage and the exchanger just falls apart.
Try opening the cabinet (make sure that the heater is off) and seeing if you can visually see where the water is coming from and the presence of any rust.
If you provide some additional information about the heater, (make, model, and size) it might be possible to further troubleshoot this unit with you.

I can hear water sloshing around in the drivers side door

If the sound seems like its in the door but is actually coming from the air vents near the door it may be a faulty heater core.

Lay z spa water pump is faulty where can I get a

Hi Im Chris From BVL Elecric,
I cover Bournemouth and surrounding areas and supply solutions to most home electrical problems.
A lovely lady customer called me out today to diagnose faulty
pump/heater that kept tripping the RCD.
After scouring the net and finding this same problem over and over again but no solution,I decided to get personal with the blighter!!!
RESULT:- problem solved,
Customer very happy,
no new parts fitted,
water heating fine now.
If you live in my coverage area,have a LAY-Z-SPA that is faulty,no or limited warranty then give me a ring and I will be only to happy to come on over and fix it for a small fee.
just think that dead spa/pool heater/pump could be heating your water again tomorrow and there is plenty of summer left to enjoy it.
You can find my details quite easily , just google BVL Electric Bournemouth

My heater also knocks when starting

Inside the exchanger is a medal vent which passes the water into the heating area. It sometimes comes loose. Weld it back in place.

If you continue to use it as is the vent will make a hole in the bottom of the exchanger and you'll pay 350 to replace it.

My bottom refrigerator is not cold. The freezer is okay.

Check to make sure the fan in the freezer compartment is working and not blocked. This delivers the cold air to the refrigerator. The fan should run every time the freezer calls for cold.
