====Steam From Top Of Machine====
If there is steam coming from the top of the machine then one of the relief valves is venting steam.

#'''If the steam is leaking from the machine while it is heating up,''' with more and more steam coming from the top as the machine heats more, then the steam is coming from the vacuum relief valve.
#*'''The vacuum relief valve is meant to vent steam until a certain amount of pressure has built up in the boiler.''' It is normal for this valve to vent steam as the machine is heating. Once enough steam pressure is built up in the boiler the valve will pop closed.
#*'''If the machine is fully heated and the vacuum relief valve is still not closing then it may need to be cleaned.''' {{{vacuum_cleaning_instr|}}}
#*'''If cleaning the vacuum relief valve has not resolved the issue,''' then the vacuum relief valve may be broken and will need to be replaced. {{{vacuum_replace_link|}}}
#'''If the steam is leaking from the machine after it is fully heated,''' then the pressure relief valve may be relieving excess steam pressure.

|PID =#*The steam boiler temperature may need to be lowered. If your machine features a pressure gauge it should not read any higher than 1.2 bar. Program the steam boiler temperature lower and lower until the relief valve stops opening and the pressure gauge reads 1.2 bar or lower.
#*'''If lowering the temperature is not helping,''' then the pressure relief valve may be stuck open. {{{relief_stuck_instr|}}}
|Gauge =##The pressurestat may need to be lowered. The pressurestat should not read any higher than 1.2 bar. 
#*'''If the pressure exceeds this level,''' the relief valve may open. The pressurestat should be lowered. {{{Pressure_stat_adj.pdf|}}}
#*'''If the pressure is down to 1 bar or less and the relief valve is still open,''' then it may be stuck open. {{{relief_stuck_instr|}}}
|#*'''The pressurestat may need to be lowered.''' If the pressure is set too high the relief valve may open. {{{pstat_adjust_instr|}}}
#*'''The pressure relief may be stuck open.''' {{{relief_stuck_instr|}}}
#*'''If the relief valve is still opening,''' then either the pressurestat or the relief valve may be broken and will need to be replaced.

This template calls the troubleshooting instructions for prosumer machines where steam is venting from the top of the unit. The steam_adjust_style parameter is used to adjust the instructions to the style of steam pressure adjustment the machine features. For machines with a PID controlled steam boiler this parameter should be set to "PID". For machines that are controlled by a pressurestat and feature a pressure gauge, this parameter should be set to "Gauge". Otherwise the instructions will default to instructions for a machine that uses a pressurestat but does not have a steam pressure gauge.
