There are several reasons for the p[roblems you have. The primary reason is that it is a European boiler. European boiler manufacturers require and assume that the unit will be disassembled, cleaned and refurbished every year as water quality in Europe is often hard water.
American owners are used to standing pilot gas heaters that could be left as is for decades without service. However, the reason for using the combi heater is to save fuel costs. Unfortunately, such devices require service often becaue the lime in the water collcts at the diverter valve and in the tubing, making the sensitive overheat switches turn the heat off to prevent damage.
The cure is to have the unit disassembled, cleaned and rebuilt periodically. This is the period after the necessary rebuild.
"AT1: There is no average or ball-park price, because different regions of countries have different shipping and labor costs. A repairman would have to see your particular situation to know whether the estimate is to include removal, patching, obstacle avoidance, permit application time, nearness to the service truck, etc. Get three estimates from local contractors recommended by satisfied neighbors."
