KitchenAid PRO LINE KPES100PM Espresso Machine- Steam Boiler does not heat up.

My machine does not heat up on the steam side. I have opened it up and determined there is current going to both sides (elements) of the steam boiler. It does not matter how long you leave it on, it does not heat up. I am very familiar with this machine having stripped it down many times. I would like to troubleshoot this issue correctly before I start replacing parts. The espresso boiler functions normally.

Test each element for the correct resistance. Check the thermal fuses for a circuit, they are held onto the top of the boiler with a screw down bracket. Check for a circuit through the thermostat.

    Resistance through both elements is 21.7. Is this normal? Can you replace elements or do you have to order a new boiler?

    I was able to push the plastic cover back from both ends of the fuse and test the resistance which was close to zero. Then it broke. Not sure if it was broken or if I broke it taking it off/ testing it. Will replace.

    There is close to zero resistance through the thermostat which I believe indicates it is good.

    Element resistance sounds about right to me, I'm in NZ and ours are wired in series, if you're 120 volt I expect they will be wired in parallel. If you need to replace an element then that will bean at the very least a new boiler top. Can you do a live test with your meter and find where the voltage stops? Our models have a relay on them down behind the coffee boiler it switches power from coffee to steam boiler as both boilers are not powered up for heating at the same time.

SOURCE: My Breville800ESXL makes steam but does not make espresso.

jejones is right. try a coarser grind. it still makes great espresso, especially if you really pack a lot of ground coffee into the filter basket. Just make sure it is a bit coarser than you would normally use for machines without the dual wall filter basket.

SOURCE: Nuova Simonelli Mac 2000 - Boiler continues to fill up

I had the same problem of the boiler filling up all the way with water and the water was coming out of every hole in the machine. Turn the machine off, drain the boiler completely,
MAKE SURE VALVE #2 is CLOSED, this is the one under the drip pan all the way to the left. Turn on the water supply to the system and turn the system ON. The cup warmer on top will come on and stay on for anywhere between 10 to 20 minutes..... let it be,,, do not turn it OFF,, it will go off automatically. That should do it!

SOURCE: Espresso machine not steaming

If the machine heats up for coffee, then the steam wand tips are probably blocked. Use a paper clip or needle to clear out the holes at the end of the steam wand.

SOURCE: Starbucks Barista (Saeco) Espresso machine Quit pumping

Hi
If it makes a noise when you turn the brew switch on you may have a blockage in the out let line. If it doesn't make a noise but every so often you may have a bad pump.

Steam Boiler not heating up - pumps cold water but won't the boiler never heats up, I suspect the thermostat or solenoid

Check the 2 thermal fuses on the top of the boiler, if they are blown replace them and the thermostat. While you are at it replace the seals in the steam boiler, there are 5 of them in that boiler. If the fuses aren't blown check the element for continuity, sometimes one will fail.

Commercial espresso machine

Sounds like the safety thermostats on the machine is tripping because the machine is overheating or the circuit breaker is tripping because machine needs more amperage.

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.

My Kitchen Aid Pro Line Espresso Machine has stopped heating the water on the espresso side. It still pumps, but it is not hot. The steamer side works fine.

Hi I have posted a service manual and a parts list here

https://rapidshare.com/files/655646388/kitenaid_service_manual_5KES100.pdf

https://rapidshare.com/files/2923830445/Kitchenaid_5KES100_Repair_Part_List_-_8212198.pdf

It sounds like the boiler element or maybe the thermostat. You have to take the top part of the machine off to get a good look at the water boiler.
I have uploaded a not very good strip guide that I got from the internet, I have used it but it makes thing overly complicated to my mind, but here it is anyway.
https://rapidshare.com/files/3189994876/KES100_strip_guide.zip

It has written instruction that relate to two diagrams in the PDF.

Won't stay on

If you mean the switch will not lock on then replace the switch and check for steam boiler leaks while you are there. Steam is the cause of most switch failures in this model.

Kitchenaid pro line espresso maker 4kpes100pm1

Pro Line Kitchenaid appliances have a 2 Year Warranty on them from the date of purchase. Parts for the espresso machine, because they are considered "non-repairable," will be difficult to find. I would contact Kitchenaid Customer Service to see what they could recommend for you.
