Always match your existing part's model number and terminal type before ordering, since boiler fittings vary even within the same brand.\r\n<h3>Vacuum Table for Ironing: Blower Fan and Parts<\/h3>\r\nA vacuum table for ironing pulls steam and air down through the board so garments press flat and dry faster, and the blower fan is the core part of that suction system. We stock the <a href=\"https:\/\/stitchpartner.com\/product\/industrial-vacuum-table-blower-fan-clockwise\/\">Vacuum Ironing Table Blower Fan \u2013 Clockwise<\/a> for replacing a worn or failed fan. Blower fans are directional, so match the rotation of your existing fan before ordering.\r\n<h3>Built for Daily Commercial Use<\/h3>\r\nBoiler steam irons run for hours at a stretch in tailoring shops, dry-cleaning outlets, and garment factories, so the parts that keep them running need to handle that duty cycle \u2014 not just light home use. We stock components rated for continuous industrial operation, not appliance-grade substitutes.\r\n<h3>Frequently Asked Questions<\/h3>\r\n<h4>Do you have a contactor for a boiler steam iron?<\/h4>\r\nYes \u2014 we stock both 18A and 25A contactors for boiler steam irons. Check your existing contactor's amperage rating before ordering, since using an undersized contactor for a high-wattage boiler heater shortens its life.\r\n<h4>What causes a steam boiler to stop heating?<\/h4>\r\nThe most common causes are a failed heating element, a tripped or worn contactor, or a water level controller board that's misreading the tank level and cutting power as a safety measure. Testing the heating element for continuity with a multimeter is usually the fastest way to narrow it down.\r\n<h4>Do you supply boiler hose pipes and clamps?<\/h4>\r\nYes, we stock boiler hose pipes and hose clamps sized for standard steam iron boiler connections. Bring your existing hose's diameter or send us a photo if you're unsure of the size.\r\n<h4>How do I know which water level controller board fits my boiler?<\/h4>\r\nWater level controller boards vary by boiler brand and probe configuration, so match your existing board's model or number of probe pins before ordering \u2014 a mismatched board can misread the tank level entirely.\r\n<h4>How much do steam iron boiler spares cost in India?<\/h4>\r\nSmall parts like seals, switches and indicator lights cost \u20b925\u2013\u20b9350. Mid-range parts like water pumps, safety valves and pressure switches run \u20b9450\u2013\u20b9800. Contactors and automatic water-level controller boards, which carry the highest electrical and safety load, cost \u20b91,200\u2013\u20b91,899.\r\n<h4>Which blower fan do I need for my vacuum table for ironing?<\/h4>\r\nCheck the rotation of your existing blower fan first, because a fan turning the wrong way moves far less air through the table. We stock a clockwise vacuum ironing table blower fan; if your table needs the other direction or you are unsure, send a photo of the old fan and its motor and we will confirm before you order.\r\n<h4>Do you have solenoid valves for boiler steam irons?<\/h4>\r\nYes \u2014 we stock a <a href=\"https:\/\/stitchpartner.com\/product\/heavy-selonoid-valve\/\">heavy solenoid valve<\/a>, a <a href=\"https:\/\/stitchpartner.com\/product\/selonoid-valve-set-for-boiler-steam-iron\/\">solenoid valve set<\/a>, a separate regular solenoid valve coil and a wire valve safety cap. Replace only the coil if the coil is dead but the valve body is sound; a leaking valve body needs the full valve or set.\r\n<h4>Will these spares fit my Akari, Messer, Silti or Silver Star boiler?<\/h4>\r\nMost of our boiler spares are stocked as replacements for Akari, Messer, Silti, Silver Star and Wejie boilers, but fittings vary, so match the part's model number or send a photo of the old part before ordering. Need only the iron for your boiler? The <a href=\"https:\/\/stitchpartner.com\/product\/2128-heavy-duty-boiler-iron\/\">2128 Heavy Duty Boiler Iron<\/a> is a 900W iron that fits all steam boilers, new and old.\r\n\r\nExplore related categories: <a href=\"https:\/\/stitchpartner.com\/product-category\/industrial-steam-iron-and-parts\/professional-bottle-steam-iron\/\">Bottle Steam Iron<\/a> \u00b7 <a href=\"https:\/\/stitchpartner.com\/product-category\/industrial-steam-iron-and-parts\/\">Steam Iron &amp; Parts<\/a>","parent":0,"count":47,"filter":"raw","image":""}],"product_tag":[{"term_id":2973,"name":"boiler water level alarm board","slug":"boiler-water-level-alarm-board","term_group":0,"term_taxonomy_id":2973,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2983,"name":"Hashima boiler board","slug":"hashima-boiler-board","term_group":0,"term_taxonomy_id":2983,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2977,"name":"industrial steam boiler PCB","slug":"industrial-steam-boiler-pcb","term_group":0,"term_taxonomy_id":2977,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2979,"name":"low water buzzer for boiler","slug":"low-water-buzzer-for-boiler","term_group":0,"term_taxonomy_id":2979,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2981,"name":"Magneto boiler board","slug":"magneto-boiler-board","term_group":0,"term_taxonomy_id":2981,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2985,"name":"Naomoto boiler board","slug":"naomoto-boiler-board","term_group":0,"term_taxonomy_id":2985,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2982,"name":"Silver Star boiler board","slug":"silver-star-boiler-board","term_group":0,"term_taxonomy_id":2982,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2972,"name":"ST-6 boiler board","slug":"st-6-boiler-board","term_group":0,"term_taxonomy_id":2972,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2971,"name":"ST-6 boiler buzzer board","slug":"st-6-boiler-buzzer-board","term_group":0,"term_taxonomy_id":2971,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2975,"name":"steam boiler alarm PCB","slug":"steam-boiler-alarm-pcb","term_group":0,"term_taxonomy_id":2975,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2978,"name":"steam generator alarm board","slug":"steam-generator-alarm-board","term_group":0,"term_taxonomy_id":2978,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2974,"name":"steam iron buzzer board","slug":"steam-iron-buzzer-board","term_group":0,"term_taxonomy_id":2974,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2980,"name":"steam iron water level alarm","slug":"steam-iron-water-level-alarm","term_group":0,"term_taxonomy_id":2980,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2984,"name":"Veit boiler board","slug":"veit-boiler-board","term_group":0,"term_taxonomy_id":2984,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""},{"term_id":2976,"name":"water level warning board","slug":"water-level-warning-board","term_group":0,"term_taxonomy_id":2976,"taxonomy":"product_tag","description":"","parent":0,"count":1,"filter":"raw","image":""}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>ST-6 Boiler Buzzer Board for Industrial Steam Iron Water Level - Stitch Partner<\/title>\n<meta name=\"description\" content=\"ST-6 Boiler Buzzer Board for compatible industrial steam iron boilers. \u20b9799 (MRP \u20b91,200).
