[FONT=&quot]Hello everyone, [/FONT]

[FONT=&quot]I'm very puzzled with an error I have on my turbomax plus 824E, [/FONT]
[FONT=&quot]I would really appreciate if you could share your thoughts.[/FONT]

I'm looking for a plumber or gas engineer advice.

[FONT=&quot]I have an intermittent F22 error.[/FONT]
[FONT=&quot]The pressure is around 1.4bar.[/FONT]
[FONT=&quot]The pump seems to be rotating ok: it's vibrating, rotating but the pump itself is always very very hot.[/FONT]
[FONT=&quot]I have replaced all NTCs and the pump capacitor but it didn't change anything.
[/FONT]
Also when measuring resistance I can see that the pump neutral and ground are connected together, is that normal ?

[FONT=&quot]the secondary heat exchanger is clean.[/FONT]
[FONT=&quot]when purging the boiler, the water is very clean.[/FONT]

[FONT=&quot]I would really appreciate if one of you has a clue ?[/FONT]

[FONT=&quot]Many thanks in advance[/FONT][FONT=&quot]

Oh, and welcome to the forum.
 
Excellent advice given above.

DIY on any gas appliance kills and we won't offer repair advice to anyone unqualified.
