Heating on top two levels but not on the ground floor

Good Afternoon,
So basically I called out a gentleman to come and have a look at our heating, as the ground was not warming up but the 1st floor and 2nd floor were working fine.
The guy bled the radiators, released any air in the system and checked that the radiators were working. All working fine.
He checked the pump which is a Grundfoss - Selectril Type UPS 15-50 130 and it seems to be working fine, however the guy did confess that it may be old or need replacing as power may not getting through the system to the ground floor. There is a diverter valve in the Cylinder system so hot water can been getting through the system however we have not used the heating during the year only recently as its been colder.
We are not sure if there is a sludge build up either. Would love some advice?
Are you a tradesperson and able to answer this question?
Sludge/debris in heating systems mainly affects ground floor level radiators first as this is the lowest point and normally the first point of impact, get yourself a strong magnet and see if it sticks to the coper pipe supplying heat to these radiators if it sticks then this is a good indication of contamination before someone tells you your whole heating system wants power flushing which is a very costly exercise, I would suggest your preferred heating engineer installs a good quality Magnetic system filter such as Adey MagnaClean Professional 2 and adds Fernox F5 which is a good chemical cleaner, the combination of the two items maybe enough to clean your system enough for there to be a noticeable improvement that you are happy with. This method is far more economical then the aforementioned Power Flush however this method is dependant on whether you have caught it in time for it to be effective!

Often enough on older systems sediment can settle at the lower levels as it’s heavier than water but a simple trick is to put your boiler on a higher setting and turn off all radiators except the affected ones on the ground floor , your pump mentioned is what’s classed as a high head pump (stronger than a normal pump )
This should be capable of moving sludge , let them run for a while until hot then gradually open up the other radiators and you should see a difference without having to go through the expense of power flushes etc although the do work
