By 'reset' do you mean that you moved it, tilted it, shut it off and back on?

open the cover on the brewer- depending on your model, it could be the front or the back cover. look for a brew timer dial. turn this up slowly, running a brew each time to see if you now have a full pot

SOURCE: water leaks out from underneath coffee maker

Well they don;t give these away for sure. Lets see if we can help you out. ? are you over filling it.This happened to me because I was reading the fill line wrong. {got new glasses} . If not may be you could try makeing less. But if only 1/2 cup comes out and no more, that wouldent indacate a leak in the tank, if there was it would all leak. Try backing off on the coffie and water, and see if it still leaks. if it does get back to me. DFD

If this unit is new and it is doing this, contact the company you purchased the unit from. They should make the adjustments needed.

If this is an old unit, and this just started, you may have a scale build up in the water supply. If that is the case, then it needs to be de-scaled.

The system uses a timer and solenoid valve for controling the water supply. If the valve is scaled up, it will not work correctly.

Also change the in-line water filter.

Hi, I just got my new rancilio yesterday and used it for the first time this morning but the coffee does not seem as hot as what I get at a coffee house or even from my former stove-top pot? I am following...

No the temperature is fixed. If you make the coffee just after is heated up 10-20 minutes then try to lush some water from filter holder first in the cup you will serve the coffee. Flush for some half a minute and the make the coffee.

Past 2 mornings, coffee maker only brewed 10 out of 12 cups.

It's probably time for a good cleaning. Follow the procedure in the manual, or get some commercially available coffee maker cleaner. When the minerals build up enough, the water flow and heating is reduced enough to keep it all from passing through.

Please take a moment to rate this solution if it's what you needed, and thanks for asking here!

The espresso side of the machine stops pumping water after 5 seconds or so. At the same time the espresso on/off button and main display start blinking. Pushing the hott water/steam button will reset this...

The clue here is that the problem involves the hot wate and the single or double espressos. These three functions require accurate water measurements and they are programmable. It appears that the flow meter is not sending the correct information to the control unit. This could happen if you have blockages or if the flow meter is not working anymore. Most likely you need a new flow meter which only costs about $20 and should not be too difficult to replace. It is located between the water tank and the pump.
