Hot water light goes off mid cycle and brewing stops.
Problem started half year ago. Boiler started leaking one month ago.
Replaced boiler but brewing still stops mid cycle, so scaling is not the problem.
Also replaced spring and glass ball in brewing unit.
Tried bigger coffee dose for more resistance and lower flow. No help either.
Can't imagine the thermostat in both the old and new boiler are defective.
Any suggestions please????

Re: brewing stops mid cycle
Sounds like dosage is too high and grind is too fine.
Rule of thumb with any saeco unit.
Do not grind any finer then 2 or your looking for trouble.
Open grinder, clean it out with a vac. Slapped it back on.
The reason it stops is grind is too fine, and the machine doesn't have enough pressure to pass threw the grinds, creates back pressure in the machine and the unit failsafes after a certain amount of time with and pressure.

Sorry this brewer is usually set up for a full pot brew. I have reset this for a small (but not half) pot brew as the customer wanted to use a metal carafe (with their own logo). I also tried once to get it to half pot brew but it can get tricky if you actually brew twice to get a full pot (in the same pot).
* there is a siphon action that starts once the boiler tank gets filled to a certain point. From that point it will continue to flow until the boiler is emptied to the level that stops the siphon action and leaves enough water in boiler to reheat for the next brew. Achieving the siphon point may be a larger volume of water for 1/2 a pot but may work for 3/4ths a pot. The 1/2 way mark may be affected by the brewers "level" while placed on a table or sagging in the middle of a weak table.
* Usually if you want a smaller brew then go with a smaller brewer. Though there is a hot water tap that will give you 2-4 cups of hot water (it gets tepid after that) which you can use for the "Mug" style brew. But it does get messy.ukeboy57
* Final, If you don't mind a little more than 1/2 pot brews then ask your vendor to adjust the machine for you. Though a reminder NOT the double brew in the same pot as it will overflow.
This means the water cannot flow through the machine. Normal fix is to
prime the machine (turn water dispenser on, fill a cup) or descale the
machine. Go through the menu, select descale, enter, then turn the steam knob fully anti-clockwise. You should put the descaling solution in the water tank first.
If you have the auto-descale in the menu then run it. Run the solution through the machine twice. Then rinse well.
Its probably time for small claims court and a new company to install good equipment. Have a couple different companies/contractors give an estimate and possibly expert advice/witness you would then be able to use in court so you can get reimbursed from a bad company. Hope it all works out.
The thermostat is cycling. This is normal as the unit has a small boiler. It is trying to maintain the temperature. It is a good idea to run some water (brew) through the portafilter before you put you coffee in to make you espresso. This will heat the portafilter, so you espresso is hot, and you get the good creama.
Your air gap is clogged, the thing sticking up from the sink next to the faucet. there is a hose that goes from the air gap to the dishwasher, somewhere in that system is clogged. You can clear it if you have a quarter inch drain snake.
bring white vinegar to a boil and pour it into the perforated top, the water reservoir and the link between the water reservoir and the brew basket. let sit a few minutes, pour it out and do it again. put the water reservoir back in, put water and vinegar solution ( half and half) in. Try to start it again. Mine did this last year and this fixed it right away. Try to clean the coffee maker using the vinegar solution once a month to avoid this problem.
