====No Hot Water From Tap====

#Check the brew function on the machine and see if water is able to flow through the machine for this function.
##If the brew water and steam are not flowing either refer to the [[#No Flow At All|No Flow At All]] section of this article
##If the brew water flows but is not hot refer to the [[#On But Not Heating|On But Not Heating]] section of this article.
#Check the steam function of the machine. If you are able to draw steam form the steam wand then the steam boiler must be pressurizing and heating.
{{#ifeq:{{{steam_gauge}}}|Yes|
#Check the steam gauge of the machine. Does it show pressure? Typical range for the steam gauge should be 1-1.2 Bar.
##If the gauge is within the 1-1.2 Bar range then the hot water tap is likely blocked. 
###Remove the tip from the hot water tap and test the flow. If flow is restored then the tip needs to be cleaned and reattached. Mineral deposits can easily collect in the screen/holes of the hot water tap, so be sure to clean these thoroughly. Soaking the tip in a solution of hot water and backflushing powder will help remove residues more effectively.
###If the flow is still blocked then there may be a blockage in the wand of the hot water tap. Clean the wand by using a pipe brush that has synthetic or plastic bristles; metal bristles can damage the wand. Then soak the wand in a solution of hot water and backflushing powder for ten minutes. Test flow again.
###If there still isn't flow then there may be a blockage farther back in the hot water circuit. The machine may need to be professionally cleaned to remove the blockage.
##If the gauge is not reaching 1-1.2 Bar, but it is pressurizing some, then the steam pressurestat may just need to be adjusted.
###When adjusting the pressurestat only slight adjustments should be made. Small adjustments will make a large difference in the pressure. {{{pstat_adjust_instr|}}}
###If adjusting the pressurestat the first time did not raise the pressure try adjusting it a few more times. If the pressure is still not raising after several adjustments then the pressurestat is likely broken and will need to be replaced. {{{pstat_rep_instr|}}}
##If the gauge sometimes reaches 1-1.2 Bar, but flicks around a lot or randomly drops to zero, or is always sitting at zero then the steam boiler is not building pressure for some reason.
###If the machine is spewing a lot of steam from the top as it is heating up then the vacuum relief valve may be stuck open. This valve is supposed to close once the machine produces enough steam pressure. {{{vacuum_relief_instr|}}}
###The high limit switch may be tripped. The high limit switch is an internal killswitch which prevents damage to the machine caused by power surges or the machine overheating. {{{hls_reset_instr|}}}
###{{{pstat_picture|}}} While the machine is open for resetting the high limit switch, check to make sure the wiring to the pressurestat isn't loose or disconnected. Reconnect the wires and see if the hot water circuit pressurizes properly.
###If there weren't any disconnected wires then the pressurestat will need to be replaced. {{{pstat_rep_instr|}}}

This template calls the instructions for handling no hot water issues on prosumer machines. The steam_gauge variable will alter the content of the instructions depending on whether the unit has a steam gauge or not. Set steam_gauge to "Yes" for machines that feature a steam gauge, and set it to "No" for machines that don't.
