Let the engine cooldown,then open the bleed screw on on the thermostat house,do not remove just loosen----fill water in the radiator bottle slowly and watch for water coming out of the bleed screw----
sometimes the bleed screw is blocked due to anti-freeze-then take the screw off completely ,clean and replace----always make sure the engine is cool

Water pump gear or the water pump impeller could have failed. If its the pump and due to it being at the bottom front side of the engine it would take some time for it to boil due to the fan is always pulling air down thru the radiator and its at the very top of engine. Cool water on top and really hot coolant around the cylinder with sensor. I'm sure it's the pump.

Why does the earth fault breaker shut down when I use my washing machine?

I assume you have checked the earth connection to the ground.usually under sink onto copper pipe.
if there is an intermittent fault on any electrical appliance then the breakers will jump and try to send any residual current to earth to save someone receiving a full force electric shock.

Condensation on the machine electrics could be a good place to start or water reaching any electrics in the same room as machine.this include moisture or damp at the wall socket

My car over heats, when it gets hot and I shut it off, the fan comes on and stays on for about 30 sec. then goes off and doesn't come back on. Is their something wrong with my relay?

The fan switch could be faulty or worse case is you have combustion fumes being pushed into the cooling jacket. Yup blown headgasket. Take to a reputable shop and have them perform a block test.
The fan could also have an intermittent fault and not kick on all the time when the relay demands it on. Good luck!

Check coolant level indicator on cadillac deville 2005 still on

After changing the thermostat you might have developed an air lock in the radiator. Does the radiator knock or push antifreeze out with the car running and the cap off. The water pump should also be checked and you can do that by looking in the radiator while running and with the cap off. You should see the fluid moving through the radiator if it is circulating Just be careful not to get burned if it pushes water out of the radiator.

I have a Bosch GWH 425 HNO propane Tankless Water Heater which began intermittently exploding when demand for hot water occurs.

Call a qualified service tech immediately.
Gas explosion indicates dirty combustion parts, and gas is not fully igniting when tankless turns on the gas. So gas builds up and then explodes causing serious damage to tankless, and serious risk to homeowner.

Shower goes hot then after few minutes cold then hot again and constantly up and down. this shower is only 2 month old and has done this since fited

it is possible that the hot mix valve needs to be adjusted higher or there is a crossed plumbing line somewhere down the line. ( just wondering(?) are you tapped off a standard hotwater tank or a hotwater on demand system ? ). also, how is the hot water throughout the rest of the house ?
