Relay soldered onto the board. Coil resistance is tad over 700 ohms. Defect possibly the contacts are worn out switching inductive load (motor) Dare say can power the relay via external 12 volt supply and check contacts make, unfortunately the variable bench power supply is at friends house. Lot...

Thanks for posting Float operates a microswitch. These sump indeed is full of water Relay is electromechanical not a triac The processor output switches the relay via interfacing transistor. Another sensor feeding into the processor causing the pump relay not to operate is a possibility hence...

My own appliance Tank full light came on and dryer was not drying the clothes. Collector tank top left was empty Removed the condenser unit and flushed both ways Removed the back and looked at the pump gubbins- float was high up and operating the switch to display the TANK FULL led Removed the...

Looks like Taco name is sticking again.

Stand corrected. Thought was a typo with that tape measure on it

You mean 5/8”?

Secondary return pump is essentially required for larger properties that have remote hot water requirements. When this tap is run, there would be significant delay before hot water gets there. A hotel is a prime example= hot water on tap is quite quick to arrive. Combi on the other hand is...

Secondary pump on an unvented cylinder NOT a combi boiler OP has a heat only boiler and cylinder.

:ROFLMAO:. If a heating engineer like Countryfan missed number 418 is not an heat only boiler ( ie not a combi- which would start with figure8) then he must be having a very bad day. Also, a system boiler would start with digit 6 and would be sealed BTW. Countryfan works with these boilers...

Fitting a secondary pump gets over the issue of delayed hot water at the tap First heat only boiler I looked at, a Glow worm minimum is 4.5kw Sure Vokera will beat that turn down ratio

Regardless of the brand, it is paramount that the boiler gets proper service instead of brand as every boiler is there to do the job. Some are better built making service a comfortable task, others are like a pigs ear and service is a pain. Know from experience as I have boiler hitting 40 year...

The display illuminating suggests low voltage present but display activation ( segments that align to create the information, not being addressed) Perhaps the display pcb if it has one? Else like above post the main pcb

Need not worry, Taco will chicken out

Coffee bean has taste and aroma that depends on multiple variables. Season, elevation, roaster, bean mix ( single or multi source) etc For humble coffee drinker elevation possibly has the biggest impact. Abundant harvest is mostly achieved at low elevation ( this is made into instant coffee)...
