Re: Isomac Rituale over pressure
Check if the pressure relief valve is working fine, if not you need to replace the valve. If valve is fine check if there is an obstruction in the lines, this can incrtease the pressure. If everything else is ok, replace the pump.

Isomac Teas domestic espresso coffeemaker, which is a well-priced warm change espresso unit perfect for the particular office or home. It has the whole metal physique in addition to all of the energy you have to help make great coffee in your own home.
I hate to say it but your element has ruptured and needs to be replaced. Notr hard to replace if you know how to get the sides off. You need to take the right side off if your facing the machine. the element screws into the side of the boiler. If you need an element I have one.
Yes you can. There's a bit of work involved. The issue is you have to remove the boiler through the top of the machine in order to access the gasket. If you're not careful, you can break one or all 3 lights because of the wires attached and the limited amount of room. I would take pics of everything before you begin. Then remove the 2 screws from the top of the machine. You can see all the wires and the brass boiler. Next remove the 4 cap screws near the brewhead where the portafilter goes. When you do this, you will see the boiler is now loose. I will let you decide how you want to do the rest. Either remove and label all the wires, or remove some of them or whatever you choose. Once you can remove the boiler, you will see that the chrome brewhead cover also comes off revealing gasket. Remove the damaged gasket, and clean the area where it sits. Put on the new gasket and put everything back. That's it. Good luck!
Some times brand new machine if they stay for months not in use then the volumetric water pressure pump is stuck. And you should remove it from the motor rotate it manualy ven use a litle lubricunt oil and put it back again then the pump can work perfect for many years.
Here's how it works.... An initial short run of the pump draws water from the reservoir into the boiler where it is heated by an electrical heating coil. There are two outputs from the boiler, one from the top runs through a pipe to a steam valve. When the steamer handle is turned, the steam valve opens and steam is piped out through the steam tube for frothing milk. The second output from the boiler is on the underside and is stopped by the normally closed flow valve. When the water in the boiler reaches the right temperature, a sensor switches on the OK light. When the light is on, the user pushes the pump switch and more water is pumped from the reservoir. The pressure in the boiler increases because the pump is trying to push in more water and this forces the spring loaded boiler flow valve to open allowing hot water to run out. As the sump filled with ground coffee is fitted to the boiler output, the water is forced through the coffee and out of the sump where it pours into a waiting cup. When enough coffee has been poured, the user switches off the pump. The boiler pressure falls and the spring on the flow valve pushes the valve shut again.------------The first three steps aren't strictly necessary for disassembly however if you're using a long handle screwdriver then removing the base makes it easier to gain better access to some of the screws. Step 1. Remove the screw on each base arm. Step 2. ... then lift and remove the arms. Step 3. Remove the two screws on the base of the unit. Unlike in this photo I would recommend you avoid resting the machine on its back unless you are sure it has been completely drained. The black plastic base can now be pulled away allowing easier access to some of the screws that will be removed later. Step 4. Undo the two screws on the top rear. Step 5. Remove the coffee tamper by pulling and twisting. Step 6. Remove the three screws. These are anti tamper screws and are star shaped with a nipple in the middle. Step 7. With these screws removed, the top may be lifted away. The hotplate on the top section is still connected by a couple of thin wires so lift it carefully. Step 8. To help with shifting the top out of the way, disconnect the hot plate/boiler heater connection. This will allow you to push the top of the unit away giving you the room you need to get inside. Step 9. Unscrew the electrical safety earth and move the earth wiring out of the way. Step 10. Use some long nose pliers to pull out the circlip that holds the boiler inlet pipe in place. Pull out the pipe to disconnect it from the boiler once the circlip has been removed.Step 11. Unscrew, remove and clean the diffuser. Step 12. Remove the two screws . The black plastic underside casing can now be pulled away (plastic tabs need to be pushed aside ). Step 13. Pulling away the plastic underside once screws and tabs are removed. Step 14. Loosen the four black Torx (star shaped) boiler screws . Water in the boiler may leak out at this point so ensure the unit is upright and a towel is placed underneath. Step 15. Remove the four nuts (three arrowed) from the underside of the boiler unit. Step 16. Lift up the top of the boiler assembly along with the steam outlet and place to one side. The two halves of the boiler assembly are sealed with a rubber gasket which should remain attached to the upper housing. Make sure this is properly in place when reassembling. Step 17. The lower boiler assembly can now be lifted out. -------- to get more detailed help click this link directly.it has all the required instructions and pictures to disassemble the unit.the model number in the link is bit different from yours but the system is very same so it will help you http://www.r3uk.com/index.php/tech-tips/34-disassembly-guides/129-delonghi-ec710-coffee-maker-disassembly-and-repair click on the link above directly.

Just a thought here...are you using the correct grind of coffee and have you tamped it thoroughly to keep the pressure up through the grounds? There are a number of sites on the web which talk about how to use an espresso maker. I'm sure you'll get the inspiration you need there to learn to do it right.
In the first months, we encountered low water to the brew head, although both the steam and hot water wands had decent pressure and flows.
Adjusting our grind, so that the coffee beans were coarser helped immensely--for awhile.
Then the problem gradually reappeared as an extremely slow brew time. Our machine was still relatively new, so we shipped it back to our place of purchase. It came back working just great and interestingly the filter in the resovoir was now filled with the filtering particulate it did not come with.
I am surmising, that however great the engineering is on the Isomac, manufacturing leaves something to be desired. Do not let your warranty expire. Pay the shipping and fix your otherwise great machine.
