Step 4 Open device
• Place the unit with the bottom facing downwards. Carefully lift the upper part.

• The upper part can now be put aside.

Step 5 Measuring the solenoid valve coils resistance
• Remove the rubber protection cap from the cable lug of the conductor.
• Disconnect both cables from the spool. To do this, use a pointed object (eg a small screwdriver) to push the lock of the cable lug outwards, and at the same time pulling the cable lug away from the valve.
• Use a multimeter to measure the resistance between the two contacts. It should (at least briefly) be at 30 ohms. If the resistance is infinite, the coil is defective and needs to be replaced.
• I could not get the coil individually. The complete valve was available here: https://shop.euras.com/detailsseite_ma.p... In the comments Maxim is showing a reasonable priced source.

Step 6 Removing the solenoid coil
• In order to disassemble the coil the valve must be turned approximately 30° counterclockwise. Replacing the whole valve doesn't make a lot of sense here, because the pressure hoses are partly glued together or are fixed in place with clamping rings.
• Remove 2 Phillips screws #1 to give the hose connected to the iron more play.
• Pull off the cable lug of the heat sensor, while pushing the pawl outwards.
• Grab the whole valve and turn it counterclockwise until the coil is able to squeeze past the black pressure hose. You may need pliers.
• Open the fixing nut turning a wrench counterclockwise and pull off the coil.
• Auf Bild 4-6 kann man den Schlauch sehen, der in den Kommentaren ab 23.5.23 besprochen wird.

Step 7
• It happens that the hose behind the solenoid valve has come loose because the plastic connector has broken.
• The connecting piece can be replaced by a suitable aluminum tube.
