Diverter valve?

[jackg]

WB 12/14 Heatslave Combi
Turned it on this morning for hot water for a shower and the rads heated up and the hot water took longer than usual to heat up.
Think this is the diverter valve which I replaced some 5 years ago and I still have the old one.
What is the remedy, to replace or will a strip and regrease solve the sticking?

Oh well. Talk to myself. Got hairs on the palm of my hand as well...
Checked the record of the last time I changed it in 2009 and it does not close fully.
To test, a pair of pliers around the pin on the top of the valve with the actuator off and the valve will move upwards about 1/4", so not full not closing.
Part no. 241361 £26 on ebay or £15 refurbed with new O rings and a clean.

Watch the attitude, we do have jobs to do

I'd just change it, refurbing isn't worth the faff

It's possibly passing due to a sludgy system. Wouldn't surprise me if you get the same problem in a few months.

Honeywell grey top diverters are rubbish, particularly so in oil heatslaves from my experience.
Replace the cartridge for now. It will go again in time, mine failed 4 times in 5 years.
