However, even the most reliable equipment can <strong>fail<\/strong> if not <strong>properly operated and maintained<\/strong>. <\/p>\n\n<p>In this article, we review the <strong>five most common electric steam boiler problems<\/strong> we see on a day-to-day basis with our customers and how to avoid them easily and cost-effectively.<\/p>\n\n<h2 class=\"wp-block-heading\">1. Damage to the resistors due to inadequate water use or lack of purging.<\/h2>\n\n<p>One of the <strong>most common failures<\/strong> is the <strong>breakage or overheating of electrical heating elements<\/strong>. This is usually due to <strong>poor water quality<\/strong> (high hardness or salt content) or <strong>lack of regular flushing<\/strong>, which causes scale build-up and incrustations. <\/p>\n\n<h3 class=\"wp-block-heading\">How to avoid it<\/h3>\n\n<ul class=\"wp-block-list\">\n<li>Use <strong>treated or demineralized water<\/strong> to feed the boiler.<\/li>\n\n\n\n<li>Install a <strong>reverse osmosis or decalcification system<\/strong> if necessary.<\/li>\n\n\n\n<li>Schedule <strong>automatic or manual purges<\/strong> at the appropriate frequency, depending on usage.<\/li>\n\n\n\n<li><strong>Visually check<\/strong> the <strong>resistors<\/strong> at each scheduled maintenance.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">2. Failures in the inlet or purge solenoid valves<\/h2>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/giconmes.es\/wp-content\/uploads\/2025\/06\/fallo-electrovalvulas-mantenimiento-calderas-vapor-1024x576.webp\" alt=\"Failure of solenoid valves in steam boilers\" class=\"wp-image-15927\" title=\"Giconmes industrial steam generators\" srcset=\"https:\/\/giconmes.es\/wp-content\/uploads\/2025\/06\/fallo-electrovalvulas-mantenimiento-calderas-vapor-1024x576.webp 1024w, https:\/\/giconmes.es\/wp-content\/uploads\/2025\/06\/fallo-electrovalvulas-mantenimiento-calderas-vapor-300x169.webp 300w, https:\/\/giconmes.es\/wp-content\/uploads\/2025\/06\/fallo-electrovalvulas-mantenimiento-calderas-vapor-768x432.webp 768w, https:\/\/giconmes.es\/wp-content\/uploads\/2025\/06\/fallo-electrovalvulas-mantenimiento-calderas-vapor.webp 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n<p><strong>Solenoid valves<\/strong> are key elements in water inlet and blowdown control. They often <strong>fail<\/strong> due to <strong>debris accumulation, internal wear or lack of cleaning<\/strong>, which directly affects boiler performance and safety. <\/p>\n\n<h3 class=\"wp-block-heading\">How to avoid it<\/h3>\n\n<ul class=\"wp-block-list\">\n<li>Performs <strong>periodic opening and closing tests of solenoid valves<\/strong>.<\/li>\n\n\n\n<li><strong>Clean or replace filters <\/strong>in the water line.<\/li>\n\n\n\n<li><strong>Replace<\/strong> solenoid valves that show <strong>signs of clogging or irregular response<\/strong>.<\/li>\n\n\n\n<li>Be sure to use <strong>original and quality spare parts<\/strong>.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">3. Problems with water levels<\/h2>\n\n<p><strong>Level sensors or probes<\/strong> monitor the amount of water in the boiler. If they <strong>become dirty, out of calibration or fail<\/strong>, they can cause constant alarms or even unsafe operation of the equipment. <\/p>\n\n<h3 class=\"wp-block-heading\">How to avoid it<\/h3>\n\n<ul class=\"wp-block-list\">\n<li><strong>Clean<\/strong> the <strong>probes or floats<\/strong><strong>regularly<\/strong>, especially if the water has impurities.<\/li>\n\n\n\n<li><strong>Verify<\/strong> that the <strong>level remains stable<\/strong> during operation.<\/li>\n\n\n\n<li><strong>Change the level sensors <\/strong>according to the maintenance schedule or at the slightest sign of failure.<\/li>\n\n\n\n<li>Uses <strong>redundant control devices<\/strong> in critical applications.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">4. Electrical and control failures due to poor maintenance<\/h2>\n\n<p>Although electric boilers have fewer moving parts than a gas boiler, the <strong>electrical elements<\/strong><strong>(wiring<\/strong>, <strong>contactors<\/strong>, <strong>PLCs<\/strong> or <strong>temperature\/pressure sensors<\/strong>) can <strong>deteriorate over time<\/strong>.<\/p>\n\n<h3 class=\"wp-block-heading\">How to avoid it<\/h3>\n\n<ul class=\"wp-block-list\">\n<li>Performs <strong>annual electrical inspections<\/strong>.<\/li>\n\n\n\n<li><strong>Check the condition of connections, insulation and relays<\/strong>.<\/li>\n\n\n\n<li><strong>Prevents<\/strong> the electrical panel <strong>from<\/strong> accumulating <strong>moisture or dirt<\/strong>.<\/li>\n\n\n\n<li><strong>Keep the control software up to date<\/strong> if the system allows it.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">5. Absence of planned preventive maintenance<\/h2>\n\n<p>Many users <strong>believe that electric boilers are \u201cmaintenance free\u201d.<\/strong> This <strong>misconception<\/strong> often leads to accumulated breakdowns, unexpected downtime and high repair costs. <\/p>\n\n<h3 class=\"wp-block-heading has-text-align-left\">How to avoid it<\/h3>\n\n<ul class=\"wp-block-list\">\n<li>Implement a <strong>preventive maintenance plan<\/strong>, on a monthly, quarterly or semi-annual basis depending on usage.<\/li>\n\n\n\n<li><strong>Records all tasks performed <\/strong>(purging, cleaning, replacement, checks).<\/li>\n\n\n\n<li><strong>Train<\/strong> in-house <strong>maintenance personnel<\/strong> or contract a <strong>specialized technical service<\/strong>.<\/li>\n\n\n\n<li><strong>Schedule regular inspections<\/strong> to detect problems before they become breakdowns.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n<p>A <strong>well-maintained electric steam boiler<\/strong> can last for <strong>many years with optimum performance<\/strong>. Common problems are easy to avoid with adequate water, frequent blowdowns and good maintenance. <\/p>\n\n<p>In <strong>Giconmes<\/strong>, in addition to manufacturing high quality boilers, we offer <strong>original spare parts and technical advice so that your installation always works at 100%.<\/strong><\/p>\n\n<p>Do you have doubts about the maintenance of your boiler?
