Replace O-ring on leaky boiler now machine trip GFCI

My boiler was leaking and spraying steam inside of the coffee maker. I replaced the O-ring on the boiler, now when I fire it up it comes on for a second and then trips the GFCI. Since these trip due to resistence I am wondering if the solder issue could be my problem. The solder points in the picture are brown on my board. Will adding more solder likely fix this or does it sound like I need a new board?

I have checked all of my wiring with a photo I took before I disassembled and everything is where it should be. I also put new heat compound on the thermostat and thermal breaker.

    I think I may have had moisture in the circuitry. After a day it stop faulting and now works fine. Thanks for responding.

    I tried the machine again after a day and it worked fine. I think I may have had residual moisture from when the boiler was leaking. Letting it sit a day must have dried it out.

If you don't have it fixed, here are some things to check.
There are some points on the back of a SL90 board that can use some more solder. If you pull the board out if its mount, and lay on its face without removing any wires, you will see in the upper left side 3 points that make a triangle. If any of these solder points have what looks like a bulls eye, you need to re-solder and add a little more to reinforce to joint. These Triacs heat when activated and can cause separation in the solder.
I am not sure that this would cause a tripping of your GFCI though. If you have a ohms meter do a reading on your element, then element to ground. You should get a reading in the 12 to 16 ohms on the element (between termanls) but no reading on your element (1 termanl) to ground.

It will need a new board. there is a short across the board and that is what is causing the trip.

Kitchenaid espresso machine tripping switches

Relay will be fine if you fix the real problem. Get some new seals (5 of them) into the steam boiler and check for leaks from the teflon tube at the top of the steam boiler. When you have it apart tip it upside down, you will be surprised how much hidden water there is.

Hi, you may have a leak inside which is dripping on an electronic part. Check it for leaks. On the boiler are blue thermal cut outs and overloads. One of these may be faulting. Use a meter to check them. Should show a closed circuit. Can check the resistance (approx 12 kOhms). I would just replace them anyway. They only last so long. Dazza REPAIRER

Water leaking from the left side

There are a few things that will leak on the left side
1. The boiler can leak if not descaled regularly or properly.
2. The steam boiler can start leaking around the o-ring gaskets or tubes.
3. The steam valve o-ring can wear out and leak.
Boiler will show whitish scale between the halves and will need to be replaced. The others are just replacing the seals or tubes.

It is leaking somewhere and is tripping the power.Can it be serviced or should I buy a new one?

Hi Derek, had a similar issue, steam leaking inside and condensing. It turned out to be an orange viton rubber 'O' ring inside a valve attached to the pump had failed and was allowing steam to escape when the unit was powered on. There is a short length of white pipe that connects the boiler to the pump via a valve, it's easy to remove the pipe, just pull the clip out of the flange at each end and the pipe will slide out. Replace the 'O' ring put the pipe back and replace the clips.

I suggest testing the machine with the top removed so you can see what is going on but as always, be extremely careful as there is mains voltage on various terminals in the machine. If you don't know what you are doing, it's best left alone and buy a new one which is only £25 more than the cost of a service

Your seals in the steam boiler are gone and it is leaking water to the switch below. The steam boiler is located just above the switch on the lower left side. You just have to replace the seals (O-rings)

Three thing can cause this problem.
First is as you mention the air valve is leaking and is only due to its 'o' ring which can be replaced or replace the whole air valve. Not any steam should be leak from it at all.
Second during winter the water supply is much colder than summer so every boiler refill then boiler heating automaticaly switch on.
Third also during winter the room temperature is lower so the boiler is cooling down faster than summer since their in not any insulation around it.
If the presurestat which control the temperature inside the boiler become more sensitive because of years of work this is not actualy a problem since is use the same energy but now in more times and more frequent but for less time each time. Unless it stuck and either you have continues heating with no stop or stuck at alway off so the machine is always cool no need to replace pressurestat.

Machine stuck in ventilate mode after aborted DESCALING. When descaling tripped circut breaker on the power circuit.

This means you probably have a leak inside. Usually the seals from not descaling enough. The steam boiler is over the power switch and will short the power switch. You can replace the seals in the steam boiler hoses, or tighten the fittings and probably save the machine, but change the water hardness setting in the menu to 4. This setting has saved many machines, but you mest descale your machine when it tells you. This also saves the machine.

Boiler not keeping pressure

mostly your boiler gasket is gone, or a line has blown might be lucky with a leaky o-ring

When I steam milk, the GFCI pops to off each time after 8-10 seconds. We have cleaned the internal components,metal filter, plastic assembly, etc . Do i need to send in for service?

Your seals or hoses on the steam boiler are bad. They are leaking on to electrical components and popping the GFCI. The problem is internal.

Saeco magic deluxe is leaking water

Either two faults, one is that the boiler is leaking ( fix this straight away as water can spray on main circuit board and short out ) very costly to repair if both needs replacing. Second the water runoff to the front tray is blocked with coffee grime . Instead of the water left over when the brewer dissengages running off to the front tray it overflows into the machine. Hope this helps
