I tried to order this part about four weeks ago, but as you didn't have it in stock, I ordered it direct from Bosch. However, when it turned-up, despite the spare-part having the correct code, it was too large for my iron. Bosch's response was less than satisfactory; they suggested replacing the steam generator. The broken locking cap that I have is very similar to that shown in the picture, but the screw-thread has an outside diameter of 15mm (the locking cap shown above (item ES753106) has a screw-thread with a 20mm diameter. Do you have any Bosch locking caps that have a screw-thread with an outside diameter of 15mm, which you could supply?
